Abstract

A new nonlinear intracavity device called a microdot mirror mode locker is demonstrated for ultrashort-pulse generation in solid-state lasers. The microdot mirror produces fast saturable absorber action by using self-focusing. Pulse durations of 190 fs are achieved in a Ti:Al₂O₃ laser. The microdot mirror mode locker is modular, preserves wavelength tunability, and can be extended to a wide range of solid-state lasers.
