The world laser market can be divided into three major regions: the United States (including North America) accounting for 55%, the European state accounting for 22%, and Japan and the Pacific region accounting for 23%. In the world laser market, Japan ranks first in optoelectronic technology, and the United States ranks second; in the laser medical and laser detection, the United States takes the lead;
1. Status of development of the US laser industry
In the field of laser medicine, the United States is a world leader. Laser medical equipment is widely used not only in the United States, but also in large quantities. Laser medical equipment in the United States is managed by the US Food and Drug Administration (FDA). Only approved registration can be used and produced, thus ensuring the products of laser medical equipment. Quality and reliability and safety. According to statistics, 2.5 million of the 21 million operations performed in US hospitals use CO2 laser scalpels, accounting for 12% of total operations. Two-thirds of outpatient clinics in the United States already have laser medical equipment. New laser medical instruments and medical technologies are emerging in the United States. For example, there are 200,000 to 250,000 disc herniation patients per year in the United States, 10-20% of which can be removed with lasers; 14 million people in the United States want to remove tattoos from the United States. There are 450,000 patients diagnosed with kidney stones, 1/3 of which are treated with endoscopic techniques or laser lithotripsy. More than 20,000 cases have been corrected with excimer laser for corneal scoring, 200-300 Molecular lasers are sold in the United States for the treatment of myopia, with an output value of approximately $80-120 million. The method of removing skin wrinkles is called skin re-smooth laser therapy, and the price per treatment in the US ranges from $800 to $4,500 (excluding insurance). The fee), which estimates the market for skin smoothness, can reach $1.5 billion, attracting at least eight companies to introduce CO2 laser systems for skin smoothing laser therapy.
2. Development status of Japanese laser industry
Japan's laser medical treatment began with Ar laser fundus coagulation, surgical carbon dioxide laser knife, medical Nd:YAG laser endoscope, etc., ushered in the first generation of light energy heat utilization laser medical. With the advancement of laser technology, the laser chemical benefit treatment method was born, which opened up the road of laser medicine. Nowadays, laser is applied in all medical fields in Japan.
Japan's Nd:YAG frequency-doubled laser (532nm) medical laser has a fundamental power of 60W and a tuned wave power of about 20W. It has been widely used in medical applications through KTP wavelength conversion.
The 2.94 micron light of the Er:YAG laser is more easily absorbed by water, Ca, P, etc. than the 10.6 micron of the carbon dioxide laser. It is often used for incision and excision of multi-water body soft tissue and osteotomy, and its performance is much better than that of carbon dioxide laser knife. . Since fiber optic transmission is possible, in the future, if the stable optical power fiber of the 3 micron band is successfully developed, it will be used for non-cutting and resection of the affected part of the body cavity. In addition, rare earth element Ho:YAG lasers have also been used.
Japan is very active in the treatment of cancer with lasers, mainly dye lasers with Ar laser excitation, flash excitation, and excimer excitation. With the development of fiber optic technology, they are an epoch-making new method for non-invasive treatment of endovascular cancer. They can also treat stenosis, occlusion, and revolution in cardiac surgery. Fiber optic laparoscopic surgery has been successfully applied to the orbit. The laser treatment of intra-abdominal disease in inoperative surgery has important and realistic significance for the structure of the elderly population.
The excimer UV beam has a good photochemical effect, suitable for non-thermal incision, resection, and can suppress the thermal denaturation and charring of the incision commonly seen in infrared beams. Some ArF lasers (angle wax has an absorption band around 193 nm) It is suitable for corneal incision and corneal surgery for ophthalmology myopia treatment, but it is still doubtful whether it can maintain the therapeutic effect. The ArF laser has excellent osteotomy function and is useful in plastic surgery. The Japanese Defense Medical University recently used a new technique in clinical trials of excimer lasers to remove severely burned (dead) skin tissue with short time, less pain, and selective control of exposure, without UV overdose and cancer.
GaAlAs laser with a wavelength of 780-830 nm and a power of 10-1200 mW is used for ophthalmic cataract, abnormal eyelid treatment, surgical skin muscle incision, neurological nerve fiber elongation inhibition, circulatory blood flow, skin temperature control, and pain relief. In the near future, once laser-excited small lasers are realized, laser medical applications will leap. The free electron laser will be the pillar of the medical field in the future and will be the representative of future medical laser equipment. The main task of laser medical treatment is to cure cancer and bring good news to the treatment of AIDS and intractable diseases.
Although Japan's laser medical research is active, the total output value of medical laser devices in Japan is about 3 billion yen, according to statistics published by the Japan Photonics Industry Technology Promotion Association. According to the current US dollar to Japanese yen, the price is less than 30 million US dollars. The share of Japanese optoelectronic devices is the smallest.
The development trend of the laser industry First, the development of laser research towards solid-state, semiconductor lasers and semiconductor-pumped solid-state lasers have become the dominant direction of laser processing equipment. Due to the high photoelectric conversion efficiency, smaller volume and more optimized optical mode of semiconductor lasers and semiconductor-pumped solid-state lasers, they are the most ideal and rapid lasers. Semiconductor lasers and semiconductor-pumped solid-state lasers have reached a maximum power of 6 kW, and have gradually realized the miniaturization and practical use of their devices. With these advantages, semiconductor-pumped solid-state lasers and semiconductor lasers are used in industrial laser processing and lasers. Medical applications and other applications have become mainstream lasers and will replace some of the traditional laser applications, such as lamp-pumped Nd:YAG lasers.
Second, the optimization effect of laser technology on product input-output ratio and technology base is more obvious, and the technical content integrated in products and services is getting higher and higher. Flying laser marking and color marking technology are favored by the market. The reason is that the control software realizes the control of different wavelengths of laser according to different color requirements, and the output of different working hours, which improves the use range of laser marking equipment. The laser marking machine recently launched by the famous German Trumpf company is equipped with a remote monitoring and testing system. Through data feedback of more than 270 detection points, the after-sales service engineers can accurately judge the operation of the equipment and implement remote diagnosis. The worries of the customers.
Third, laser technology is combined with many emerging disciplines to be closer to people's daily lives. Laser cosmetic technology is favored by more and more women, reflecting the integration of laser technology with other disciplines and the expanding scope of applications.
Fourth, the laser industry mergers and acquisitions are prevalent, and companies strive to become industry giants. Through the merger and restructuring of the well-known German Trumpf company, there are 7 companies engaged in the production of laser products, including the well-known Haas company. Coherent sold its medical laser group to Israel's ESC/Sharplan in early 2001 and purchased several companies specializing in industrial laser manufacturing, specializing in technical research and product development in the industrial laser field. Lumenis, a consortium of ESC/Sharplan and Coherent, has no one in the world in the field of medical lasers. The formation of these large enterprises has promoted the laser development technology and industry to a new stage of development. On the other hand, it also shows that these manufacturers are seeking a monopoly on the cutting edge of laser technology.
