Products Introduction
ECL100 External Cavity Diode Laser (ECDL) in Littrow configuration is designed based on research progress of cold atom physics[1],[2]. The principle of the ECDL reveals that the laser emission mode is enhanced by the optical feed back with a blazing grating, which restricts the spectrum of lasing mode by its narrow dispersion distribution and dominates the competition of the laser mode. The external cavity laser implements better performance both in single longitudinal mode and line-width comparing with PF configuration diode laser. In the Littrow configuration of the external cavity diode laser, the output laser beam is coupled by the “0th” order diffraction one of the blazing grating while the optical feedback beam is formed by the “1st” order one. ECL100 external cavity diode laser offers advantages in simple structure, reliable, easy operation and inexpensive. To fit customer’s requirements on laser frequency stabilization, the function for current modulation and cavity (or PZT) modulation is available, furthermore its mode hop free tuning range is extended by feed forward technique[3].
