Abstract :
The wavelength of a commercial red pointer laser diode has been tuned over 4 nm digitally in 0.2 nm steps with a folded telescopic grating loaded external cavity incorporating a liquid crystal pixel mirror. The sidemode-suppression ratio of the laser was better than 20 dB throughout this range
