| titleOfInvention | High power femtosecond laser with adjustable repeat frequency |
| abstract | An adjustable repetition frequency laser engine (1) comprising: an oscillator (100) that generates and provides a beam of so-called femtosecond seed pulses; an extender that extends a duration of the seed pulses; and an amplifier (300) that: receives the extended seed pulses from the extender, amplifies an amplitude of selected extended seed pulses to create amplified extended pulses, and provides an amplified extended pulse laser beam; wherein the amplifier (300) comprises a dispersion compensator that reduces a dispersion of the amplified extended pulses; a compressor for compressing a duration of the amplified extended pulses; said expander and said compressor being an integrated expander-compressor device (200) comprising a so-called volume modulated Bragg diffraction grating (CVBG) adapted to: receive the seed pulses (211) at an extremity; extend a duration of the seed pulses (211) by introducing different delays for the "red", "green" and "blue" components of these "white" seed pulses, producing extended seed pulses (212), with the colors "blue" and "red" referring to the parts of the infrared spectrum that have shorter and longer wavelengths within the pulse bandwidth; receiving the amplified extended pulse laser beam (213) at its opposite end; compressing a duration of the amplified extended pulses (213) by delaying their "red" components relative to their "blue" components or vice versa, to the same degree that they were delayed during the extension stage; and providing an amplified compressed femtosecond pulse laser beam (214) with a pulse duration of less than 1000 femtoseconds; and said amplifier (300) comprises: an optical cavity that is coupled to the extender-compressor (200) to receive and circulate the extended seed pulses in a determined number of roundtrip paths, an optical switching device (330, 340 ) coupled to the optical cavity to control the coupling of the light of the extended seed pulses received in the optical cavity and to control the coupling of the light inside the optical cavity exiting in the form of amplified extended pulses, where the Optical switching device is configured to control and adjust the number of round-trip paths of light that is coupled within the optical cavity to control and adjust a pulse repetition rate of the amplified extended pulses provided by the amplifier , an optical gain means (310) within the optical cavity to amplify the extended seed pulses into extended pulses amplifies two, and a dispersion compensator within the optical cavity to compensate for a dispersion of the amplified extended pulses introduced by optical elements (310, 321-324, 330, 340) of the amplifier within a round-trip path of the light inside the optical cavity of the amplifier, excluding scattering induced by the scattering compensator, wherein said induced scattering is quantified as a group delay scattering (GDD); |
