Detection of the occurrence of multiple pulses in a LD pumped soliton laser

摘要

The identification method involves actuating an ultra short pulse laser system in a soliton regime. A signal is measured that is proportional to pulse power or pulse energy detected by a resonator circulation for laser emission. Another signal is proportional to the quadrate of the pulse power averaged by the resonator circulation. An undesired dual or multiple pulse condition (DP or MP) is measured based on a comparison of the measured signals, which are independent in an area of the resonator circulation periods, and the latter signal is detected. Independent claims are also included for the following: (1) a method for preventing dual or multiple pulse conditions and optimizing laser operating point (2) a measuring device for recognition of dual or multiple pulse conditions in an ultra short pulse laser system for generation of femtosecond or picoseconds pulses.
