Classification: CPC H | IPC H

Claim 13:
14. A method according to claim 13 wherein the semiconductor laser is tuned by:
using a combination of the heater currents H1, H2 to sweep a range of wavelengths;
adjusting base temperature T of the laser by changing the current of the substrate heater to shift a gain maximum;
adjusting laser currents I1, I2 to achieve a selected light output level;
adjusting a ratio between the laser currents I1, I2 to achieve an optimal side mode suppression ratio;
performing another sweep by varying the combination of heater currents H1, H2; and
repeating the foregoing until an entire gain of the laser material is covered.
