    摘要: There is provided a solid-state laser device (10) including: a resonator; a solid-state laser medium (18) disposed in the resonator; an excitation section that irradiates an excitation beam into the solid-state laser medium (18); a mode selector (26) that controls transverse modes of oscillating light in the resonator; and a movement section (28) that moves the mode selector (26) along the resonator optical axis direction (Z).
    The laser may be mode-locked with a SESAM (12) and the laser medium may be Yb: KYW. The transverse mode selector may be a knife edge (26) which is translated with the help of a holder (28) resulting in a single transverse mode emission of the laser.

    摘要: In certain embodiments, a system (10) comprises a laser source (20), one or more optical elements (24), a monitoring device (28), and a control computer (30). The laser source (20) emits one or more laser pulses. The optical elements (24) change a pulse length of the laser pulses, and the monitoring device (28) measures the pulse length of the laser pulses to detect the change in the pulse length. The control computer (30) receives the measured pulse length from the monitoring device (28), determines one or more laser parameters that compensate for the change in the pulse length, and controls the laser source (20) according to the laser parameters.
