Semiconductor lasers are found throughout everyday life.  They are especially prevalent in the communications industry, where the beam from semiconductor lasers propagates down  a fiber optic.  Semiconductor lasers can also be found in CD players.

    In this lab we investigate the properties of a semiconductor diode laser.  Specifically we will look at the following

bullet

The way in which the output power of the laser varies with the applied diode current.

bullet

The way in which the spectrum of the laser varies with the applied diode current.

bullet

The dependence of the peak wavelength of the laser with varying temperature.
