摘要： A method for use in controlling emission of an optical pulse from a laser comprises pumping a gain medium (10) of a laser at a rate which is limited so that free-running passive Q-switching of the laser is prevented regardless of a duration of pumping of the gain medium. The method further comprises triggering a saturable absorber (12) of the laser so as to reduce a laser cavity loss below a laser cavity gain and cause an optical pulse to be emitted from the laser at a desired emission time. Such a method may provide for the reduction of pulse-to-pulse timing jitter, the control of energy of the emitted optical pulse and/or for the suppression of the emission of multiple optical pulses that may otherwise occur for free-running passive Q-switching of the laser for sufficient gain medium pumping rates.

摘要： A method for use in controlling a passively Q-switched laser apparatus (110) comprises triggering pumping of a passively Q-switched laser apparatus at a pump trigger time, measuring an emission delay between the pump trigger time and a time of emission of a Q-switched optical pulse from the laser apparatus. The method further comprises using the measured emission delay and a target time for the emission of a further Q-switched optical pulse from the laser apparatus to determine a further pump trigger time. The method may be used for improving the timing of emission of Q-switched optical pulses and may, in particular, serve to suppress pulse-to-pulse timing jitter in particular, though not exclusively, for laser target designation. The laser comprises an end mirror (122), an active gain medium (126), a passive Q-switch (128), an output coupler (124), a beam splitter (146), a photodetector 144), the electrical signal (148) of which is evaluated by a controller (140). The controller provides information to the laser diode driver (132) which drives the laser diode (130) emitting light (136) for pumping the active gain (126). Jitter in the repetition rate of the passively Q-switched laser can be reduced by pump power control.

摘要： A laser (10) includes a pump source (12) that provides pump energy at a first wavelength and a laser cavity (14). The laser cavity includes a laser gain medium (16) that receives the pump energy from the pump source and creates gain at a second wavelength different from the first wavelength, and a mode stripping portion (18) coupled to the laser gain medium. The mode stripping portion causes the laser cavity to have a low Fresnel number so as to allow only the lowest-order fiber mode to resonate in the laser cavity. Higher-order fiber modes are discriminated against so as to generate a laser output (22) having a substantially diffraction limited beam in a single transverse mode at the second wavelength.

The saturable absorber 14 and the mirror 21, integrated into one body, constitute a saturable absorber mirror 23. The gradient index lens 15 converges the light output from an end face of an optical fiber 32 and outputs the light to the saturable absorber mirror 23, and inputs the light reflected from the saturable absorber mirror 23 into the end face of the optical fiber 32. Thus, there is provided a pulse fiber laser device that enables easy adjustment of the intensity of light incident on a saturable absorber and facilitates miniaturization.
