Abstract

A high repetition rate, high energy tunable and line narrowed alexandrite laser was designed and built. It utilized two 6.35 mm by 100 mm laser rods in tandem. The laser rods were operated at 90°C. A novel short pulse generation technique using an acousto-optic Q-switch was incorporated. Thermally induced lensing was counter-balanced by incorporating curved ends onto the laser rods. The associated astigmatism was corrected using a cylindrical lens between the laser rods. The laser has been operated at 110-130 Hz, 400 mJ output energy, 0.05A linewidth, and 1-3 μsec pulse duration for many hours.
