Brandnew have announced the release of 1273nm-1653.7nm Laser Diode for gas detection, using Tunable Diode Laser Absorption Spectroscopy (TDLAS) systems. This laser is available as a high performance “14 pin Butterfly” or “TO39” component (with integrated TEC and isolator).
This DFB-LD (including DFB-type semiconductor laser) is a laser that utilizes the Bragg reflection of a diffraction grating formed along an active waveguide to unify the laser longitudinal mode. It provides high wavelength stability and narrow linewidth. Setting the pitch of the diffraction grating enables the required wavelength to be obtained.
