Abstract
The technical problem to be solved is to provide a kind of new type electro Q-switch.One new type electro Q-switch of the present invention, including Electro-optic crystal,Transmission medium.It is an advantage of the current invention that: electro-optical Q-switch voltage can effectively reduce, and the polarization state no requirement (NR) that device is to incident illumination, it is possible to evade the drawback of conventional electro-optical Q-switch, possess again conventional electric-optically Q-switched advantage simultaneously.
Description
Technical field
The present invention relates to field of lasers, particularly to a kind of new type electro Q-switch.
Background technology
Q-regulating technique is through making the Q-value in chamber in time by the technology of certain procedures change someway.Start in pumping
Time make chamber be in low reactance-resistance ratio state, i.e. improve oscillation threshold, make vibration not generate, the inverted population of upper energy level just can be big
Amount accumulation, when running up to maximum (saturation value), makes suddenly the loss in chamber reduce, and Q-value is uprushed, and laser generation is set up rapidly
Come, within the extremely short time on the inverted population of energy level be consumed, be changed into the light energy of intracavity, the outfan in chamber is with list
Energy is discharged by one impulse form, then just obtains the giant-pulse laser output that peak power is the highest.The method adjusting Q has very
Many, the most electric-optically Q-switched, acousto-optic Q modulation, tune Q passive Q-adjusted, mechanical etc..
In numerous Q-regulating techniques, electric-optically Q-switched is a kind of widely used technology.The electric-optically Q-switched of routine is by electricity
Photo effect so that incident illumination phase place changes, by Selecting phasing, thus reaches final q-effect.But conventional electric light Q
There are two obvious drawbacks in switch: 1, half-wave voltage is higher；2, polarized light modulation can only be realized.Thus it is actual at some
In application process, it is impossible to the advantage well playing its high velocity modulation Q, it is desirable to provide a kind of improvement adjusts Q voltage and polarization
Unrelated electro-optical Q-switch.
Summary of the invention
The technical problem to be solved is to provide a kind of new type electro Q-switch.
A kind of new type electro Q-switch of the present invention, including Electro-optic crystal,Transmission medium.
It is an advantage of the current invention that: electro-optical Q-switch voltage can effectively reduce, and device to the polarization state of incident illumination without wanting
Ask, it is possible to evade the drawback of conventional electro-optical Q-switch, possess again conventional electric-optically Q-switched advantage simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention a kind of new type electro Q-switch.
Detailed description of the invention
The invention will be further described the most in conjunction with the embodiments.
As it is shown in figure 1, a kind of new type electro Q-switch, including Electro-optic crystal,Optical transmission medium.WhereinLight
The refractive index of transmission medium is slightly less than The refractive index of electro-optic crystal such that it is able to create conditions for total reflection.Applied
Cheng Zhong, incident illumination is incident with total reflection angle, when When electro-optic crystal is not added with voltage, its refractive index does not changes, entirely
Reflection does not destroy, and optic path is normal；When During electro-optic crystal making alive, its refractive index changes, thus destroys
Total reflection so that the loss of the original optical path direction of propagation is bigger.The most repeatedly, it is placed in the middle of resonator cavity and can be realized as q-effect.
