Abstract:
A method and apparatus for detecting and controlling the conditions needed for starting and maintaining mode-locked operation of a laser system including a fiber oscillator and high power fiber amplifier. The invention is used to monitor the output power and repetition rate of the fiber oscillator and control the operation of the oscillator such that the oscillator obtains and maintains correct mode-locked operation despite changes in environmental conditions such as temperature, and also with changes due to component aging or degradation.
