摘要
A theoretical study on the influence of cavity parameters on pulse properties of dual wavelength Yb: YAG mode-locked laser has been carried out. Using coupled rateequations, the relations of the small signal gain to the cavity parameters are simulated at first. The calculation results are taken into Haus's master equation to investigate the effects of cavity parameters on the properties of dual-wavelength mode-locking pulses. The results show that, increasing the cavity length, output coupling rate and beam radius in the laser crystal in a proper regime is benefit for pulse energies enhancement, and the pulse widths will be broadened very little.
