Recording of Robust Holographic Optical Elements in Glass

Narrow linewidth continuous wave diode-pumped Tm:YLF laser with a volume Bragg grating

“…The VBG was recorded in a photo-thermo-refractive (PTR) glass and the process of Bragg grating recording in PTR glass was described in some publications [11,12]. Recently, volume Bragg gratings (VBGs) have attracted a great deal of interest for wavelength selection in laser diodes [13], solid state lasers [14], optical parametric oscillators (OPOs) [15] and fiber lasers [16].…”
