Description
Technical field
The utility model belongs to the semiconductor laser application, relates to a kind of multi-wavelength high-power semiconductor laser light-source system, can be applicable to laser medicine.
Background technology
Laser medicine is as a key areas of laser applications, develops very fastly, progressively moves to maturity.Volume is little, in light weight because of having, the life-span is long, low in energy consumption for semiconductor laser, wavelength covers wide characteristics, is specially adapted to the manufacturing of Medical Devices
The semiconductor laser wavelength scope is wide, and the semiconductor laser irradiating biological tissue of different wave length can produce different biological effects, and corresponding different laser methods of treatment is applied to the treatment of various disease
In the medical cosmetology field, one of main application of laser is exactly a laser depilation, has developed quite ripe in American-European developed country.The depilation Wavelength of Laser is good with 694-1064nm, and common wavelengths has 755nm, 800nm, 1064nm and 694nm clinically, and is the most common with the above two, and these wavelength are the matrix of hair shaft, hair follicle epidermis and the compound pigment of heating deep optionally.
There is theory to think; When optical maser wavelength is in the color base absorption peak; Its photon energy is transferred to and finally has on the clinical effectiveness color base molecule, and that color base competition on every side absorbs is minimum, and when pulsewidth is equal to or less than the thermal relaxation time of this tissue; The thermal effect that laser produced only limits to target tissue, and does not cause the surrounding tissue fire damage.In laser depilation, the melanin granule of hair follicle and hair is the target color base of this laser, and laser destroys hair matrix through destroying hair follicle, stops hair regeneration.
The pulsewidth of laser, energy and wavelength are the important parameters that directly influences the laser depilation effect.Color base reduces along with the increase of wavelength the absorption of laser, so the short more laser of wavelength, and color base absorbs strong more.But the melanin of the epidermis laser absorption to the short wavelength too is very strong, so the degree of depth of the long laser penetration reply of ripple is dark more.
The laser depilation system of commercial application has at present: ruby laser (wavelength 694nm), alexandrite laser (wavelength 755nm), semiconductor laser (wavelength 810nm) and accent Q neodymium doped yttrium aluminium garnet laser (wavelength 1064nm).Wherein the semiconductor laser depilation has been proved to be a kind of safety and efficient laser depilation mode.
According to estimates, the laser depilation operation of carrying out in the global range in 2010 reaches 5,000,000 person-times, and the 810nm semiconductor laser can produce thermal effect well by intrafollicular melanin absorption, destroys hair follicle, is the standard of laser depilation.But for the different colours of skin, different hairs, when carrying out laser depilation, the optical maser wavelength of selecting for use is also different.
Semiconductor laser is the skin reconstruction operations in another important application of beauty treatment fields, is used for smoothing wrinkle, tender skin.The laser of 1450nm wavelength is by the moisture absorption in the dermal collagen tissue, produces thermal effect, and the regeneration of stimulation collagen and reinventing makes the skin smooth delicacy that becomes, and recovers elasticity.1.0 the laser of micron waveband, can be used for treating freckle, traumatic pigmentation, dispel tatoo, eyebrow tattooing, informer etc. are black, the cyanine pathology; 0.5 the laser of micron waveband is used to treat nevus flammeus, shallow-layer coffee spot, dispels redness, brownly tatoos, red, brown pigmentation pathology such as eyebrow tattooing, lip tattooing.Wavelength is that the semiconductor laser low-intensity irradiation of 800～900nm can stimulate the local blood circulation, promotes cell to grow, improve immunity, alleviating pain and promote wound healing etc., has been widely used in rehabilitation and physiotherapy.
The most frequently used thermal source is the semiconductor laser that produces the 810nm near-infrared laser in the ophthalmology; The laser piercing power of this wavelength is strong. and refractive media is minimum to its absorption; And the adjustable scope of hot spot is bigger; Domestic and international a lot of research report shows that low-power 810nm semiconductor laser can be used for treating various intractable glaucomas, silicone oil injects the intractable high intraocular pressure of postoperative, and amphiblestroid light coagulates and fixing etc.
Full-fledged along with semiconductor laser technique. the continuous expansion of laser wavelength range, self distinctive advantage constantly increases. and it also in continuous expansion, has almost covered the range of application of other laser in the application of medical field.It has not only remedied high energy CO laser and has been difficult for Optical Fiber Transmission, unhandy shortcoming, and has remedied the shortcoming that lamp light-pumped solid state laser efficient is low, heat radiation bothers, and is expected to become the main flow of medical laser.
The apparatus for laser depilation of Chinese patent Granted publication number Japanese Ya Mang Co., Ltd utility model for CN1452465 discloses.This device adopts power output 5mW-1500mw, and the semiconductor laser of wavelength 600nm-1600nm loses hair or feathers, because system's power output is low, spot size is little, and wavelength output is also non-adjustable, and depilation efficient is very low.
Publication number is a kind of multifunction laser beauty treatment of the patent of CN1498601A machine; It uses solid state laser, and it can only realize the output of two different wave lengths as light source; If will realize the output of two above wavelength, it is that Machine Design or optical design all will be very complicated.
