Volume Bragg Grating Assisted Broadband Tunability And Spectral Narrowing Of Ti:Sapphire Oscillators

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 similar to 200 mW output power. (C) 2009 Optical Society of America
