VBG Locker is a reflecting volume Bragg grating, which can withstand high optical energy
recorded in a photosensitive silicate glass.
It is used as the mirrors placed in laser resonators to lock the wavelength of the laser, select the horizontal mode and longitudinal mode, and narrow the
laser line width and improve the operating temperature range of the laser. Working wavelength
and the specific dimension can be customized according to customers' requirements
