  • Method and apparatus for obtaining and maintaining mode-locking in fiber laser systems
    Publication number: 20060146892
    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.

  • Method and apparatus for controlling and protecting pulsed high power fiber amplifier systems
    Publication number: 20050225846
    Abstract: An electronic circuit for controlling a laser system consisting of a pulse source and high power fiber amplifier is disclosed. The circuit is used to control the gain of the high power fiber amplifier system so that the amplified output pulses have predetermined pulse energy as the pulse width and repetition rate of the oscillator are varied. This includes keeping the pulse energy constant when the pulse train is turned on. The circuitry is also used to control the temperature of the high power fiber amplifier pump diode such that the wavelength of the pump diode is held at the optimum absorption wavelength of the fiber amplifier as the diode current is varied. The circuitry also provides a means of protecting the high power fiber amplifier from damage due to a loss of signal from the pulse source or from a pulse-source signal of insufficient injection energy.
