摘要
Laser activity of neodymium-doped gadolinium scandium aluminum garnet (Nd:GSAG) on the 4F3/2 → 4I9/2 transition with an output wavelength around 943 nm was investigated. The emission cross-section was measured with spectroscopic and amplifier approaches demonstrating the applicability of the Nd:GSAG laser for water vapor detection. A Q-switched laser setup delivered 150 ns pulses with 26 mJ output energy and 9% optical to optical efficiency. The laser was diode pumped with up to 50 Hz repetition rate. In the long pulse mode a pulse energy of 83 mJ with 32% optical efficiency was achieved. The output wavelength was controlled by injection seeding.
