Wide-bandwidth mode-hop-free tuning of extended-cavity GaN diode lasers [PDF]
, 2005 We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode ...
