Distributed Bragg Reflector (DBR) lasers are semiconductor laser diodes designed to provide stable, narrow-linewidth emission at a defined wavelength. A Bragg grating integrated into the laser cavity acts as a wavelength-selective reflector, enabling precise control of the emitted wavelength and high spectral purity.
DBR lasers are well suited for applications that require high wavelength stability, narrow linewidth, and low-noise optical sources, including cold atom spectroscopy, Raman spectroscopy, interferometry, metrology, and sensing.
