Abstract
The invention provides a 1210 nm optical parameter oscillator, relating to the photoelectron technical field. The oscillator consists of an input mirror, a small aperture, two nonlinear optical crystals and an output mirror set. The oscillator generates the laser with the length of 1210 nanometers which can be up to the laser power necessary to burning fat after amplified. The optical parameter oscillator is an all solid state laser with high efficiency. Compared with a free electron laser, the optical parameter oscillator can greatly lower the medical cost and has the advantages of low cost, compact system, etc. Therefore, the optical parameter oscillator has good market propect.
Description
Technical field
The present invention relates to the photoelectron technology field.
Background technology
Along with the raising of living standards of the people, the overweight people is on the increase, and except the elderly, also is no lack of the teenager.In China, the beginning of the nineties, the number of obesity was also turned over some so far.Obesity not only becomes the primary health problem of individual, also becomes the big problem that the mankind will face.In this year, the researcher of Jefferson Lab studies show that the absworption peak in the absorption spectrum of fatty 800-2600nm wavelength, and the fat that 1cm is dark under the epidermis is more than 2 times of epidermis to the laser absorption of 1210nm wavelength, and not damage of epidermis when dispelling fat.The laser of this wavelength and burning fatty effect, the laser of other wavelength all do not have the good of 1210nm, so will have very big demand.And the laser crystal that directly produces 1210nm optical maser wavelength at present yet there are no report, and what Jefferson Lab used is that free electron laser makes a search.This laser power is low, the cost height.
The 1210nm optical parametric oscillator of our invention, adopting 532nm laser is pumping source, the KTP optical parametric oscillator of noncritical phase matching is realized the laser of output 1210nm.Parameteric light reaches after amplifying and burns the required laser power of fat.This optical parametric oscillator is the high-efficient full solid-state laser, compares with free electron laser, can reduce medical treatment cost greatly.
Summary of the invention
The objective of the invention is to design the optical parametric oscillator of a kind of KTP output wavelength 1210nm of 532nm pumping noncritical phase matching.
This optical parametric oscillator is made up of pumping source, resonant cavity, aperture and KTP nonlinear optical crystal.Its structure as shown in drawings.The invention is characterized in that the KTP nonlinear optical crystal that is adopted adopts noncritical phase matching θ=90 °, φ=81.6 °; The parameter light wavelength that produces is 1210nm.
The optical maser wavelength of said pumping source is 532nm;
Said resonant cavity chamber mirror, the parameteric light that nonlinear crystal is produced by coating technique forms single resonance in the chamber, also can realize double resonance;
Said aperture can carry out modeling to parameteric light again to the pump light modeling in resonant cavity;
Said nonlinear optical crystal makes optical parametric oscillator export the laser of 1210nm by specific phase matched.
The 1210nm laser that above-mentioned optical parametric oscillator produces can reach after amplifying and burn the required power of fat.Compact integral structure, cost are low, have the very strong market competitiveness.
Description of drawings:
Accompanying drawing is the example pie graph of 1210nm optical parametric oscillator of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiments of the present invention are described further:
1 is that output wavelength is a 532nm laser pumping light in the accompanying drawing; 2 is the input mirror of optical parametric oscillator, and plating is high saturating to the 532nm wavelength, to flashlight and the high anti-deielectric-coating of ideler frequency light; The 3rd, aperture, clear aperature is 3 millimeters, it places after the input mirror, can carry out modeling to parameteric light again to the pump light modeling; The 4th, the KTP nonlinear optical crystal adopts noncritical phase matching θ=90 °, φ=81.6 °.Pump light is pumping nonlinear crystal KTP behind mode selection by pinhole, and flashlight can starting of oscillation in the chamber like this, and noncritical phase matching produces e
2Parameteric light; 5 is the K9 glass outgoing mirror of optical parametric oscillator, and plating is to the high deielectric-coating anti-, that signal light wavelength is partly seen through of 532nm wavelength and ideler frequency light; 6 is 1210nm laser.
After starting pumping laser, the staff changes the energy storage of power supply according to concrete need of work, just can obtain the parameteric light of different-energy (power).
