New Solid State Lasers for Applications in Lidar Systems
A compact, pulsed diode-array-pumped Nd:YAG laser is described which can be used as a transmitter laser in remote sensing systems. The laser is side pumped with quasi-cw linear diode arrays close coupled to a zigzag slab laser crystal . When pumped at 24mJ a pulse energy of llmJ was achieved for free running operation, corresponding to a slope efficiency of ηslope=47%. Results of q-switched operation and intracavity second harmonic generation are presented. The laser can be used as a basis device to generate radiation at many other wavelengths.
