Abstract
A compact programmable tuning external cavity laser has been developed using a microprocessor as the controller in which a stepper motor is employed to execute the motions of the grating for wavelength continuous tuning and a dual stage Peltier cooling system as precise temperature controller. A tuning range of 77 nm and 1GHz/microstep tuning resolution are achieved. This device can be widely applied to spectroscopy, spectral measurements, metrology, remote sensing, and so on.
