Abstract

An injection-locked Ti:sapphire laser is developed, with injection locking achieved using the Pound-Drever-Hall technique. By measuring the dependence of output power on the pump power with various Ti:sapphire laser parameters, we experimentally studied the influences of the ring cavity length, the focal length of the pump-laser mode-matching lens, and the output-coupler transmission on the threshold and slope efficiency. The dependence of the output power on the master laser power is also investigated. The present study provides a guideline for developing a Ti:sapphire laser with high slope efficiency and low threshold.
