VCSEL-pumped gain module


For QCW DPSSL gain module gain distribution, pumping efficiency and life time are three most important indices. The gain distribution has two effects on beam quality. On one hand the energy density distribution sets the distribution of the gain and the nonuniform gain distribution result in changes of intensity distribution in near field; On the other hand thermal effect in the gain medium cannot be ignored at high frequency. Uniform energy density means uniform heat density and the wave-front distortion is parabolic, which can be regarded as a lens and compensated easily.
While nonuniform energy density results in high order distortion which is hard compensated for and reduces the focusing ability of the beam. In multi-pass amplifier these effects come worse.


 


Based on several-year efforts on DPSSL gain module and our VCSEL technology, Laserconn can provide DPSSL gain module with uniform gain distribution, high pumping efficiency and a long life time. We have two types of gain module, namely water-cooled cylindrical gain module and all solid state gain module. We also provide customized gain module.
