报道了一种宽调谐窄带钛宝石振荡器。利用腔内的体布喇格光栅实现了可调谐和光谱窄化。可调谐范围从785 nm到852 nm，同时保持光谱线宽小于10 pm，基本上没有光谱抖动。只有2个纵模在852 nm处振荡，在垂直入射时，光栅提供了大约200 mW的输出功率。
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.
