Abstract： |
The invention is a kind of double-wavelength compound pump method of a kind of board laser gain media and the gain model, which belongs to high-power solid laser technology field. The character of the invention lies in: the pump lights with two different wavelengths are coupled from any two pairs of surface in the three pairs of surfaces of the laser gain media into the gain media laser gain media has double imbibition peaks or several imbibition peaks structure, it realizes the high power output of the solid laser. The invention overcomes the restrain that the single pump wavelength can only uses a single pump method, it also upgrades the injected pump power, improves the uniformity of the pump energy distribution, thus, it can acquires high power laser output, improves the beam quality of the output laser. The invention can be used as the gain model of the laser primary grade; it also can be used as the gain model of the laser amplified grade. |
