Abstract(in Japanese) (See Japanese page)
Abstract(in English) We investigate the laser efficiency in a mode-locked Yb:YAG laser with an intra-cavity highly nonlinear medium by using nonlinear Schrodinger equation. We confirmed optical-to-optical conversion efficiency become larger as output coupler transmittance increases but the pulse width become broader. And because we assume the gain spectrum with parabolic shape in this research, the loss between oscillation spectrum and gain spectrum at the skirt of waveform affects laser efficiency.
