摘要： A laser assembly is provided that includes a laser resonator that emits a first light having a first pulse width, and a trigger assembly electrically coupled to the laser resonator to actuate the laser resonator. The laser assembly also includes a sensor configured to detect the first light as the light emits from the laser resonator, and one or more processors coupled to the trigger assembly. The one or more processors are configured to obtain a first time delay interval from when the trigger assembly is actuated to when the sensor detects the first light, and actuate the laser resonator to emit a second light having a second pulse width based on the time delay interval determined.

摘要： In a general aspect, a chirped optical pulse is compressed by operation of diffraction gratings and a dispersive mirror having a smooth reflective surface. In some aspects, a chirped pulse laser system includes a programmable optical dispersive filter (PODF) operable to modify a spectral phase of optical pulses and a pulse compressor that receives an optical pulse based on an output of the PODF. The pulse compressor includes optical elements in a vacuum chamber. The optical elements define an optical path through the pulse compressor, and are arranged to disperse the optical pulse in the optical path. The optical elements include diffraction gratings and a dispersive mirror, which has a smooth reflective surface that defines a portion of the optical path.

摘要： A laser system includes a master oscillator, which emits a train of optical seed pulses with variable intervals between the pulses. An optical power amplifier includes an optical gain medium, which receives and amplifies the optical seed pulses from the master oscillator, and a pump, which applies pump radiation to the optical gain medium. A pulse generator applies a control input to the master oscillator, which causes the intervals between the optical seed pulses to vary by at least 50% at a rate of change that is greater than a response frequency of the optical gain medium. A control unit drives the pump responsively to predicted intervals between the optical seed pulses, at a variable pump power selected so that the pulse amplitudes of the output pulses vary by no more than 20% irrespective of the varying intervals between the optical seed pulses.

摘要： The disclosed invention relates to a pulsed iodine laser apparatus. The laser apparatus has a flashlamp-pumped iodine laser oscillator which produces a laser pulse with a full pulse width of longer than 1 microsecond, and a COIL amplifier. The laser apparatus may has a controller which controls the timing of injecting chlorine gas contained in a high-pressure chlorine tank into the singlet oxygen generator by outputting an open/close signal of the valve V2, and the timing of injecting iodine molecules contained in a iodine molecule tank into an amplifier chamber of the COIL amplifier.

摘要： A beam combining device comprising at least one beam splitter and phase adjustment circuitry. The at least one beam splitter comprises a semi-reflective surface, first and second inputs, and first and second outputs operatively connected to receive first and second light beams. The semi-reflective surface has first and second sides positioned such that light entering from one input is partially reflected through one output and partially transmitted through another output. The phase adjustment circuitry adjusts the relative phases of the first and second light beams so that light transmitted through the semi reflective surface from one input may be adjusted to have a phase which can cancels or constructively adds to light reflected from another input. Light having a combined power of the light beams, or a fraction thereof, may be selectively emitted through a selective output depending upon the adjustment of phases. Also, a method of operation is claimed.

摘要： In a case where the period from the input of the output suspension instruction to the next output instruction is shorter than the fixed period of time, the seed laser light source and the pumping light source are in a pre-pumped state during the period from the end of the output state to the start of the next output state. In a case where the period from the input of the output suspension instruction to the next output instruction is longer than the fixed period of time, the seed laser light source and the pumping light source are in the pre-pumped state only for the fixed period of time from the input of the output instruction.
