Abstract
A laser configured to selectively operate in two different operational modes is disclosed. In the first operational mode the laser is configured to output femtosecond laser pulses and in the second operational mode the laser is configured to output nanosecond laser pulses.
Claims27
A laser comprising an oscillator, a pulse stretcher, an amplifier comprising a cavity, and a pulse compressor, wherein the laser is configured to selectively operate in two different operational modes:
- a first operational mode wherein the laser is configured to output femtosecond laser pulses, wherein, in the first operational mode, the oscillator is configured to generate seed pulses in the femtosecond range, the pulse stretcher is configured to generate temporally stretched pulses from the seed pulses, the amplifier is configured to operate in an amplification mode and provide amplified pulses, and the pulse compressor is configured to compress the amplified pulses temporally down to produce femtosecond pulses;
- and
- a second operational mode wherein the laser is configured to output nanosecond laser pulses, wherein, in the second operational mode, the cavity of the amplifier is configured to generate nanosecond pulses.
