  • Laser arrangement and a method for generating power pulses
    Patent number: 7496117
    Abstract: A laser arrangement including a gain fiber to provide nonlinear amplification, the gain fiber having a first end and a second end, a dispersion adaptation fiber having a first end and a second end, and an output coupler is disclosed. The first end of the dispersion adaptation fiber is connected to the first end of the gain fiber, and the second end of the dispersion adaptation fiber is connected to the second end of the gain fiber, thereby forming a laser cavity. The dispersion adaptation fiber has a length in relation to a length of the gain fiber such that the laser cavity has a net group velocity dispersion which is positive or below a predetermined threshold, and the dispersion adaptation fiber further includes a compression fiber providing nonlinear compression and having a first end and a second end. The first end of the compression fiber is connected to one end of the gain fiber and the second end of the compression fiber is connected to the output coupler.

The first end of the dispersion adaptation fiber is connected to the first end of the gain fiber, and the second end of the dispersion adaptation fiber is connected to the second end of the gain fiber, thereby forming a laser cavity. The dispersion adaptation fiber has a length in relation to a length of the gain fiber such that the laser cavity has a net group velocity dispersion which is positive or below a predetermined threshold, and the dispersion adaptation fiber further includes a compensation fiber providing nonlinear compression and having a first end and a second end. The first end of the compensation fiber is connected to one end of the gain fiber and the second end of the compensation fiber is connected to the output coupler.
