You are purchasing the Laser diode and primary optics to a External Cavity Wavelength Tunable Diode Laser 1520nm - 1630nm. Depending on your implementation you will need to supply additional parts to have a working system. The parts supplied are enough to build a basic manually tuned laser capable of demonstrating how wavelength can be changed from 1520nm - 1630nm. Only persons skilled and knowledgable in class 1m lasers should purchase this product. These parts were surplus from New Focus (Newport) the company that built the laser subsystem for the Agilent 81960A or B: Parts Included: Laser Diode Prisim Defraction Grating Laser Diode Specifcations Laser Type = ECL-Laser InGaAsP Wavelength range = 1505 nm-1630 nm CW output power = 50 mW Beam waist diameter = 9 ?m Numerical aperture = 0.1 Laser Class according to IEC 60825-1 (2001)- Intl. = 1 M General Theory This External Cavity Tunable Diode Laser's cavity is based on the Littman-Metcalf design shown in the third photograph for this listing, The Laser uses a diffraction grating at grazing incidence to provide wavelength selectivity. Integrated into the laser diode supplied are the is the (AR) coating on the front facet of the diode. The AR coating turns the diode into purely a gain element. A collimating lens also integrated into the laser diode assembly directs the output of the diode across a diffraction grating at grazing incidence. The retroreflector (prism) in the laser cavity reflects the first-order diffraction off the grating to provide feedback. Dispersion derived from the grating allows only one cavity mode to lase, resulting in a very narrow linewidth. The specular reflection or zero-order diffraction off the grating serves as the output beam of the laser. The angle between the grating and the end mirror determines the lasing wavelength. Tuning is achieved by varying the angle of the end reflector. Continuous (mode-hop free) tuning requires selecting an appropriate pivot point. References T. Day, F. Luecke, and M.
