The cooling system are indispensable components for high power laser transmitter. The laser system ensures compact, lightweight, energy-saving is a major challenge in laser manufacturing. This paper presents a novel thermal design for our compact high peak power Yb:Er:glass laser. The cooling system is based on thermoelectric cooler with heat dissipation of the TEC's hot side using vapor chamber, heat sink and fan. The finite element analysis is applied for temperature distribution simulation. The simulation model is calibrated by experiment results to ensure that the error is less than 6%. The laser with cooling system stably operates at the peak power of 1 MW, the repetition rates are tunable from 1 Hz to 20 Hz, and the operation temperature range is from -20 °C to 60 °C.

We report on a high average power and high repetition rate nanosecond pulsed eye-safe KGW Raman laser intracavity driven by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Taking advantages of the carefully selected two-composite-laser-crystal configuration, the thoroughly optimized gate-open time of acousto-optic modulator and the ingeniously designed U-shaped resonator, substantial power and efficiency enhancements as well as superior mode matching have been enabled. Under the injected pump power of 64.5 W, the average output powers of the first-Stokes fields at 1496 and 1527 nm can be up to 8.1 and 9.5 W with 25 kHz repetition rate and 3.2 µs gate-open time, respectively, corresponding to the optical power conversion efficiencies of 12.6% and 14.7%. Meantime, the resultant pulse widths are determined to be 4.6 and 6.3 ns with the peak powers of approximately 70 and 60 kW, respectively. The beam quality can be maintained with M2 < 1.5 across the entire output power range.
