Medical Multi-Wavelength Lasers

Abstract

The invention discloses a medical multi-wavelength laser device. In one case, the multi-wavelength laser is generated by the fundamental frequency light through a modulator, and a resonant cavity is generated by a selective reflection mirror and a total reflection mirror, and the structure is compact. . It is also possible to expand the diversity of output wavelengths through simple frequency doubling combined with the cooperation of the above-mentioned selective reflector and total reflector, which is easy to expand. The selection and adjustment of multiple wavelengths depend on liquid-optic switches and shutters, which are easy to adjust and work safely and reliably. Another situation is to further include a second total reflection mirror for the laser with the first output wavelength inclined at 45 degrees on the projection optical path of the second selective reflection mirror. Through structural integration, it is convenient to adjust and obtain in multiple directions, and the structure tends to be more compact.

Description

technical field [0001] The invention belongs to the technical field of medical laser equipment, in particular to the technical field of side-pumped all-solid-state multi-wavelength lasers. Background technique [0002] Laser energy is highly concentrated in time, space, and spectrum, making it widely used in many fields. Among them, medicine is the earliest, most extensive and most active subject that applies laser technology. Countries around the world have developed many kinds of laser medical equipment for different therapeutic purposes and used them in clinical treatment. [0003] In the early application of laser in clinical medicine, because there were not many types of lasers, there was not much room for choice. Often, lasers of one wavelength were used for all surgical operations, and the entire surgical process was completed with the help of conventional instruments. To meet the special needs of each process of surgery, can not get the best treatment effect. Wit...

Problems solved by technology

The two laser wavelengths obtained by this method use five crystals, whose structure is quite complicated and difficult to manufacture, so it is difficult to be applied in practical applications.

[0009] In addition, there are methods such as using argon ion laser, dye laser or krypton lamp pumped laser, semiconductor laser direct emission, adjustable cascaded frequency doubling crystal pulsed solid-state laser and other methods to obtain multi-wavelength laser, mostly low-power applications in military, detection and other fields, have not been practically applied in medical treatment
