n this thesis I discuss the construction and initial testing of an external cavity narrow-bandwidth diode laser system consisting of an external cavity diode laser and a diode laser controller. The laser is continuously tunable, without mode hops, over a range of 11 nm, and is capable of producing greater than 13 mW of power with an expected bandwidth of less than 1MHz. The controller supplies both current for the laser and a means of regulating the laser temperature and is capable of providing up to 100 mA and temperature control to... |
