    • Abstract
  • The temporal characteristics of a gain-switched Ti:sapphire laser pumped by a frequency-doubled Q-switched Nd:YAG laser have studied experimentally at the range of the pump level(pump energy/threshold energy)from 2.1 to 3.8,the cavity length from 20cm to 60cm.According to the theoretical model of the temporal characteristics for the gain-switching laser oscillator,the buildup time and pulse-width of the oscillating mode depend on the pump level and the cavity length,inversely as the cavity loss,and also is not dependent on the pump pulse-width and the waveshape.The experimental result coincides well with the theoretical analysis.The laser oscillator with a short cavity length L=20cm pumped by a 10 ns pulse-width Q-switched laser outputs a 4ns shorter laser pulse.
