Volume Bragg Grating (VBG) Laser Diodes
Volume Bragg Grating (VBG) Laser Diodes: the Volume Bragg Grating provides the wavelength stabilization and narrow linewidth of these laser diodes. As opposed to diffraction gratings (made on the surface of an optical element) Volume Bragg Gratings are written on the inside of the material. Furthermore, the grating is usually placed not directly in front of the laser diode but after a collimating lens. In short, this is important for pumping of certain solid-state lasers, where the laser crystal exhibits efficient pump absorption only in a narrow wavelength range.
Our Products
Our Volume Bragg Grating Laser Diodes provide Narrow Linewidth, CW output in the Red and Near Infrared (NIR) spectral regions. Furthermore, these laser diodes provide up to 750mW for our Single-mode options and up to 400W for our Multimode options. Finally, we provide options for free-space or fiber-coupled output and package options, including TO-can, butterfly and more.
