Abstract
This invention relates to an end side pump batten laser technology characterizing that the output beams of a laser diode array are focused to enter into a batten gain medium after passing through a pump coupling system, in which, the focal point is out of the gain medium, namely, pump light enters into gain medium in a divergence way, and the thickness of the medium is no longer equal but changed steadily and two big faces are polished. Pump light is distributed uniformly in the batten after total inner reflection and combined with a stable/non-stable mixed cavity to get output laser of high power, high efficiency and high beam quality, which is suitable for lasers of high power output and thermo stable operation or high power amplifiers.
Description
Invention field
Belong to laser technology field.
Technical background
End face part pump bar gain media is a kind of important method that obtains high efficiency, high power, the output of high light beam quality laser in conjunction with stable/astable hybrid chamber.This device adopts two big face heat radiations; Oscillating laser straight-line pass gain media.This part end pumping mode, generally be pump light to be focused into sheet incide in the lath medium, form the heavy pumping district in lath medium central authorities like this, on the direction vertical with the pumping line, very big temperature gradient will be formed, under the certain situation of gain media size, the increase of I/O power there is bigger restriction.
Summary of the invention
The objective of the invention is at all solid state slab laser device, adopt a kind of novel battened construction, can make higher pump power be coupled into the lath medium, and on lath small size direction, pump light is more near evenly distributing, therefore thereby laser gain is also even relatively, reduces the temperature gradient in this direction, helps importing, the raising of power output.Simultaneously, can be in conjunction with stable/astable hybrid chamber, to obtain the laser output of high power, high efficiency, high light beam quality.
The present invention is by laser diode pumping source, the lath gain media, and stable or stable/astable hybrid resonant chamber is formed.The output beam of laser diode array focuses on and enters the lath gain media behind pumping coupling system, and focus is in the gain media outside, and promptly pump light enters gain media with the form of dispersing; Lath thickness changes gradually along optical direction, and two big mirror polish utilize total internal reflection that pump light more is bordering on uniformly and are distributed in the gain media.Two big faces contact with heat sink, pass through heat conducting and radiating
Advantage of the present invention is: the present invention is a kind of novel all solid state slab laser, pump light forms in lath more uniformly by total internal reflection and distributes, in conjunction with stable/astable hybrid chamber, to obtain the laser output of high power, high efficiency, high light beam quality.The present invention is particularly useful for laser and the heat steady operation laser or the high power amplifier of high power output.
