【Abstract】 The five mirror cavity of diode pumped Yb∶YAG Kerrlens mode-locked laser was analyzed theoretically in this paper.To get stable self-mode-locking in the experiment,the best parameters of the cavity had to be found.Compared the five mirror cavity with the four mirror cavity,it was found that the mode-locking was much more stable in the five mirror cavity.The reasonable explanation of five mirror cavity stable mode-locking was given in this paper by using stability region theory.And the Kerr-strength of the five-mirror cavity was calculated.It would provide a theoretical method for the modulation of the diode pumped kerr-lens mode-locked laser.更多还原
