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.

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.

The active layer includes a first layer including aluminum gallium indium arsenide ((Al x Ga 1-x ) y In 1-y As, where x and y are greater than or equal to zero but less than one), and a second layer including aluminum gallium indium arsenide ((Al m Ga 1-m ) n In 1-n As, where m and n are greater than or equal to zero but less than one, and at least one of m-x and n-y is not zero). The spacer layers includes aluminum gallium indium phosphide ((Al a Ga 1-a ) b In 1-b P, where a and b are greater than or equal zero but less than one). The plurality of semiconductor layers and the active layer held between the spacer layers are laminated.
