Volume Bragg Grating assisted broadband tunability and spectral narrowing of Ti:Sapphire oscillators

Opt Express. 2009 May 11;17(10):8212-9. doi: 10.1364/oe.17.008212.

Abstract

A widely tunable, narrow band Ti:Sapphire oscillator is reported. Tunability and spectral narrowing were achieved by use of a volume Bragg grating in the cavity. Tunability was observed from 785 nm to 852 nm while maintaining a spectral linewidth less than 10 pm with essentially no spectral jitter. Oscillation on only 2 longitudinal modes is also reported at 852 nm with the grating at normal incidence providing approximately 200 mW output power.
