Abstract
An optical parametric generator comprises a seed laser feeding an optical system. The seed laser is arranged to provide a seed beam at either a signal frequency of a signal wave or an idler frequency of an idler wave. Further, the optical parametric generator comprises a pump laser of a defined type feeding the optical system. The pump laser emits ultra-short optical pulses as a pump wave. In addition, the optical parametric generator comprises a second order non-linear crystal of a defined type arranged in the optical system. The defined type of the crystal and the defined type of the pump laser are selected so that the signal wave or the idler wave are locked in an edge of the pump wave.

An optical parametric generator comprising:
- a seed laser feeding an optical system, wherein the seed laser is arranged to provide a seed beam at either a signal frequency of a signal wave or an idler frequency of an idler wave;
- a pump laser of a defined type feeding the optical system, wherein the pump laser emits ultra-short optical pulses as a pump wave, wherein the ultra-short optical pulses emitted by the pump laser are less than 1 picosecond in duration;
- and
- a second order non-linear crystal of a defined type arranged in the optical system;
- wherein the defined type of the crystal and the defined type of the pump laser are selected so that the signal wave or the idler wave are locked in an edge of the pump wave.
A method of controlling an optical parametric comprising a seed laser feeding an optical system, a pump laser of a defined type feeding the optical system, wherein the pump laser emits ultra-short optical pulses as a pump wave, wherein the ultra-short optical pulses emitted by the pump laser are less than 1 picosecond in duration, and a second order non-linear crystal of a defined type arranged in the optical system, the method comprising the steps of:
- arranging the seed laser to provide a seed beam at either a signal frequency of a signal wave or an idler frequency of an idler wave;
- and
- selecting the defined type of the crystal and the defined type of the pump laser so that the signal wave or the idler wave are locked in an edge of the pump wave.
