    摘要： A laser oscillator to generate a pulsed light beam includes an output coupler mirror, configured to reflect a reflected portion of the pulsed light beam back into the laser oscillator, and to couple an outputted portion of the pulsed light beam out from the laser oscillator; an end-mirror, configured to return the pulsed light beam into the laser oscillator; a gain material, positioned between the output coupler mirror and the end-mirror along an optical path, configured to amplify the pulsed light beam; a self-starting saturable absorber, configured to self-start a pulsed mode-locking operation of the laser oscillator; and a pulse-shaping saturable absorber, configured to shape pulses of the pulsed light beam into laser pulses with a pulse length of less than 1,000 femtoseconds.

    摘要： A semiconductor laser device includes: a semiconductor laser array in which a plurality of active layers that emit laser lights with a divergence angle ¸ S (>4°) in a slow axis direction are arranged in the slow axis direction; a first optical element that reflects first partial lights advancing to one side in the slow axis direction by a first reflecting surface and returns the first partial lights to the active layers; and a second optical element that reflects partial mode lights of a plurality of mode beams of second partial lights advancing to the other side in the slow axis direction by a second reflecting surface and returns the partial mode lights to the active layers, the first optical element is disposed such that the first reflecting surface forms an angle equal to or greater than 2° and less than (¸ S /2) with a plane perpendicular to an optical axis direction of the active layers, and the second optical element is disposed such that the second reflecting surface forms an angle greater than (-¸ S /2) and equal to or less than -2° with the plane perpendicular to the optical axis direction of the active layers.

    摘要： Disclosed is an ASE-free continuously tunable external resonator laser in which reduction in tuning range and decrease in O utput are suppressed. The external resonator laser comprises: a fixed support body which has a half mirror that partially reflects incident light and partially t ransmits incident light fixed therein; and a rotatory support body which is rotat ably supported by the fixed support body by way of a shaft, and which has a laser chip that emits light, a collimator lens that collimates light emitted from the laser chip, and a diffraction grating that diffracts light emitted from the la ser chip, fixed therein.
