Abstract
An injection-seeded Nd:YAG laser with long pulse duration was designed and built. Single-frequency was achieved through ramp-fire technique. Long folded cavity and large pump spot was adopt to achieve long pulse duration and high energy. The laser operated at 200Hz. The pulse duration of about 80ns and pulse energy of 1mJ was achieved. The laser will be applied in a coherent Doppler wind lidar.
