Löhring, A. Meissner, D. Hoffmann, A. Fix, G. Ehret, M. Alpers] A diode-pumped Q-switched and injection-seeded single-frequency laser, generating tunable laser radiation at 935nm, is presented. Using Nd:YGG (Y3Ga5O12) as the active medium, the laser that was developed to serve as a transmitter for water-vapor lidar measurements. The configuration consists of a stable resonator in rod geometry that is injection seeded by a narrowband diode laser and stabilized by the ramp-and-fire technique. Energy scaling was done in a power amplifier in slab geometry. Both oscillator and amplifier crystal were diode pumped at 806nm. More than 30mJ pulse energy at 100Hz repetition rate with a beam propagation factor of M2<1.4 and pulse duration of 52ns in single-frequency mode were generated. To our knowledge this is the first direct generation of 935nm Q-switched pulses from Nd:YGG suitable for water-vapor measurements. The reported results show great promise of this laser in applications where high efficiency and reduced complexity is indispensable, such as for spaceborne or airborne water-vapor lidar instruments.
