Analytical expressions of quadratic and cubic phases in a three-element resonator for Kerr-lens mode locking

摘要

We present analytical expressions of quadratic and cubic phases in a three-element resonator for Kerrlens mode locking. Variation of quadratic and cubic phases with wedge angles of Ti:sapphire and apex angles of a prismatic output coupler are calculated. The results provide a theoretical basis for the design of a three-element cavity.
