Volume Bragg Grating (VBG)

Volume Bragg Grating (VBG) Laser Diodes Overview

Volume Bragg Grating (VBG) Laser Diodes. Narrow Linewidth. Many Wavelengths and Output Powers to choose from.

Volume Bragg Gratings is the wavelength stabilization of lasers, most often found on laser diodes. The grating is usually placed not directly in front of the laser diode but after a collimating lens. This is important for pumping of certain solid-state lasers, where the laser crystal exhibits efficient pump absorption only in a narrow wavelength range.
