PASSIVELY MODE-LOCKED FIBRE PULSED LINEAR LASER (VERSIONS) Russian patent published in 2015 - IPC H01S3/67 

FIELD: physics.

SUBSTANCE: passively mode-locked fibre pulsed linear laser comprises a pumping radiation source, a radiation polarisation supporting fibre linear resonator, comprising series-arranged spectrally selective reflecting element, a collimator, a fibre end which does not reflect laser radiation back to said fibre, an amplifying fibre, at least one fibre spectral information module for inputting pumping radiation into the resonator, at least one polarisation-dependent splitter for outputting radiation from the resonator, a fibre end which does not reflect laser radiation back to said fibre, a collimator, a radiation focusing optical element and a resonator mirror. The resonator mirror is placed on the flat surface of laser radiation-transparent optical element with Kerr-type nonlinearity and thickness greater than 0.5 mm, the second flat surface of which is located between the mirror and the radiation focusing optical element and has an inclination angle greater than 1 degree to the axis of the laser resonator.

EFFECT: enabling generation of short-pulse radiation in a wide spectral range without limitations on the service life of the laser.
