    An investigation of the properties of the GaAs diode laser
    (University of New Brunswick, 1981) McInnis, Rodney Mark; C. Linton
    The purpose of this project is to operate a commercial diode laser within its specifications and study a few properties within the framework of elementary physics calculations. The laser diodes used have some restrictive power supply parameters and exceeding them can easily destroy a laser. Experimental objectives could only be achieved after several pieces of electronic equipment were designed and built, such as the temperature regulator, Hex. display, avalanche photodiode detector and power supply, and laser power supply. Upon completion of the hardware, the diode laser was examined under the following experiments: -spectral distribution above and below threshold current -mode structure - peak wavelength as a function of temperature - spectral distribution at different peak currents -beam divergence -threshold current as a function of temperature
