Evaluation and adjustment of the laser loss due to the voltage across gain medium

摘要

By monitoring the voltage across [challenge] laser gain medium (12), and a system and method for evaluating or testing the optical loss characteristic relates to a laser. It also is determined by the loss of [SOLUTION] resonator monitors the voltage across the gain medium (12), the loss profile of the resonator is adjusted in accordance with the voltage across gain medium (12) , a method of operating a laser and laser.
