Abstract
The invention provides a method and laser system for switching from a current operating point to a new operating point of the laser, the laser operating at a particular wavelength and includes a source channel and destination channel. The system switches and locks the output wavelength of a laser at ultra fast time scales (<50 ns) and compensate for degradation in the laser, and thermal transients in the device during the switching to ensure that within a certain time the laser has switched its wavelength to another wavelength within a specific accuracy and is not dependent on the previous wavelength of the laser.
