Background technology
At present, in recent years, wavelength 1064nm/532nm laser becomes the (as: tattoo of (as: pigmentation, chloasma etc. after nevus of Ota, Ito's nevus, Mongolian oak, cheekbone portion Fuscocaeruleus, coffee spot, freckle, seborrheic keratosis, macle, junctional nevus, melanose, ble nevus, inflammation) and dna exogenous pigment skin problem at treatment endogenous pigment dermatoses, tattoo eyeline, tattooing lid margin, skin lesion with pigment aspects such as xlip and accidental tattoo) obtain the clinical effectiveness attracting people's attention.
8ns, single pulse energy maximum reaches 1J.If the laser of 1064nm wavelength is through KTP frequency-doubling crystal, thus acquisition 532nm wavelength laser, and single pulse energy maximum reaches 400mJ's.The laser of the 1064nm/532nm wavelength of moment transmitting can efficiently smash pathological tissues color base, be photic explosion: the laser of 1064nm/532nm wavelength within the utmost point short time (<8ns) momentary action in target tissue, it is cracked that corresponding color base absorbs the luminous energy very fast expansion moment explosion of being heated, after a part (epidermis) color base is cracked, excrete from epidermis, a part (epidermis is with in undertissue) color base is fragmented into can be by the fine particle of macrophage phagocytic, after being digested by macrophage, finally excrete by Lymphatic Circulation, the color base of pathological tissues will reduce gradually until disappear, and normal surrounding tissue due to do not absorb or seldom absorb 1064 the laser of 532nm wavelength, therefore almost not damaged, painful little, most people are without anesthesia.Recover fast, little to normal work influence.After-operation response is little, only has slight swelling, in several days, can disappear.Laser sterilization, without cross-infection, does not need special treatment environment.So electric-optically Q-switched laser is because the real continuous adjustable doctor of its single pulse energy can obtain energy density arbitrarily (facula area constant situation under) for clinical.
But traditional 1064nm/532nm laser therapeutic apparantus has 1064nm and two varifocal treatment heads of 532nm, according to clinical needs, often will change treatment head, troublesome poeration.Change frequently the useful life that has reduced treatment head, also caused the reduction to a certain degree of Laser output energy.
Because above-mentioned defect, the design people, actively research and innovation in addition, to founding a kind of laser of automatic switchover wavelength of new structure, makes it have more the value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide the laser of a kind of wavelength that automatically switches in a kind of useful life of improving treatment head.
The laser of a kind of wavelength that automatically switches of the present utility model, comprise: 45 spend the eyeglass that is all-trans, housing, laser oscillator and helm gear, wherein, 45 spend the eyeglass that is all-trans, laser oscillator and helm gear are all arranged on housing, 45 spend the eyeglass that is all-trans is connected with the Nd:YAG rod of the amplifying stage of laser oscillator, laser oscillator is connected with helm gear with 45 degree total reflective mirrors respectively, laser oscillator is made up of total reflective mirror, wave plate, electric-optically Q-switched box, polarizer, Nd:YAG rod and outgoing mirror, and electric-optically Q-switched box is connected with total reflective mirror; This helm gear comprises KTP frequency-doubling crystal, and eyeglass is spent in two laser filterings 45; KTP frequency-doubling crystal is spent eyeglass with two laser filterings 45 and is connected.
By such scheme, the utility model at least has the following advantages:
Switch trouble in order to solve optical maser wavelength, avoid the replacing of handle, simplify the operation, according to Theoretical Design, and in conjunction with a large amount of experimental studies, by increase a helm gear in 1064nm Laser output light path, this helm gear comprises KTP frequency-doubling crystal.By the control of electronic equipment, can make ktp crystal insert in 1064nm laser optical path, thereby produce the frequency doubled light of 532nm wavelength, conversion efficiency can reach 40%; Also ktp crystal can be withdrawn to 1064nm laser optical path, thus output 1064nm laser.Facilitate wavelength switching, raising 1064nm turns the conversion efficiency of 532nm wavelength, carries high power output.By electronic equipment automatic switchover wavelength, simple and quick, it is high that 1064nm turns 532nm efficiency, and good airproof performance is reliable and stable, easy to maintenance.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
Brief description of the drawings
Fig. 1 is the structural representation of the laser of a kind of wavelength that automatically switches of the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Shown in Figure 1, a kind of laser of the wavelength that automatically switches, comprise: 45 spend the eyeglass 1 that is all-trans, housing 2, laser oscillator 4 and helm gear 9, wherein, 45 spend the eyeglass 1 that is all-trans, laser oscillator 4 and helm gear 9 are all arranged on housing 2, 45 spend the eyeglass 1 that is all-trans is connected with the Nd:YAG rod 7 of the amplifying stage of laser oscillator 4, laser oscillator 4 is connected with helm gear 9 with the 45 degree eyeglass 1 that is all-trans respectively, laser oscillator 4 is by total reflective mirror 6, wave plate, electric-optically Q-switched box 5, polarizer, Nd:YAG rod 7 and outgoing mirror 3 form, two Nd:YAG rods 7 use between the two by single xenon flash lamp pumping, electric-optically Q-switched box 5 is connected with total reflective mirror 6.This helm gear comprises KTP frequency-doubling crystal 7, and eyeglass 8 is spent in two 1064nm laser filtering 45.By the control of electronic equipment, can make ktp crystal 7 insert in 1064nm laser optical path, thereby produce the frequency doubled light of 532nm wavelength.Have more wavelength needs, also helm gear can be withdrawn to 1064nm laser optical path, thus output 1064nm laser.In order to prevent contamination by dust eyeglass, cause exporting the reduction of energy, use seal chamber to seal light path.While designing cavity, adopt vibration proof measure simultaneously, prevented from causing due to vibration the skew of eyeglass, caused the reduction of Laser output energy.
Operation principle of the present utility model is as follows:
First laser is connected to control terminal (comprising control circuit and water route).Then add high pressure xenon lamp is carried out to pre-burning.After pre-burning success, by control terminal, xenon lamp is discharged to heavy current pulse, xenon lamp is excited by heavy current pulse, discharges intense pulsed light.Intense pulsed light is absorbed by Nd:YAG rod, produce population inversion, energy storage is at upper laser level, at current impulse end, electric-optically Q-switched box adds high-voltage pulse signal, because the loss of laserresonator reduces rapidly, the energy that is stored in upper laser level is released in a short period of time, thus output Q-switched pulse.The laser of oscillator output is through laser amplifier level, energy is amplified, and has obtained the 1064nm laser of macro-energy, short pulse duration, high-peak power.When needs are exported the 532nm light time, control terminal provides 532nm helm gear movable signal.532nm helm gear inserts in 1064nm laser optical path, thus output 532nm light.Act on skin from the laser of laser output through light-conducting arm and focus head.
