Abstract:
An external cavity laser system comprising:a semiconductor diode laser; temperature control means for controlling temperature of said laser; current control means for controlling injection current of the laser; an external cavity having wavelength selection means and cavity length selection means, positioned to provide feedback to said laser; said external cavity being coupled to said laser for measuring and transmitting an output of the system over a range of operating parameters; means for controlling said temperature control means, said current control means, said cavity length selection means, and said wavelength selection means to obtain arbitrary frequencies of operation of the laser system within the tuning range of said laser; said control means including varying means for varying selections made by said temperature control means, current control means, cavity length selection means and wavelength selection means in discrete increments; and, means for recording a set of discrete values corresponding to said increments and a corresponding system output of the laser system to form a table of operating characteristics.
