摘要： A system, apparatus, and method may provide laser beams of two or more wavelengths from diode pumped solid-state laser sources (220, 222, 224). The beam paths of these laser beams with different wavelengths, which are generated by the laser sources (220, 222, 224), may be aligned along a common optical axis 280 by an optical configuration, to treat at least one target area. Frequency-doubled laser beams, output from a plurality of diode pumped solid state laser cavities, may be passed through fold mirrors (M2, M5, M8), and combined on a common optical axis 280, using one or more combiner mirrors (M10, M11, M12), to unify the beam paths. Selected laser beams may be delivered to a target using one or more delivery systems.

摘要： A storage time measurement unit 46 accepts as time measurement timing signals a reference pulse CP from a Q switch control unit and a high-frequency oscillation control signal ec from a sequence control unit 42, to measure the storage time corresponding to each reference pulse. A pulse order count unit 48 accepts a reference pulse CP as a count object signal from the Q switch control unit and a Q-switching control signal qc as a count period control signal from the sequence control unit 42, to count the order of each reference pulse in a pulse train. On a reference pulse CP (i) basis, a degree of modulation control unit 50 receives storage time measurement data T G(i) and order value count data fed respectively from the storage time measurement unit 46 and the pulse order count unit 48, and based on the above measurement data T G(1) , and on a desired setting value (a fixed value) from a setting unit, computes the degree of modulation [MD] corresponding to that reference pulse CP (i) . Then, a degree of modulation control signal mc corresponding to the thus obtained degree of modulation [MD] is imparted to the Q switch control unit.

摘要： A laser safety control system is configured with a power source module directly coupled to an AC source. The power source module includes a galvanically isolated DC/DC converter, which has at least one output capacitor, and a safety mechanism. The safety mechanism is configured with first and second safety channels which operate independently from one another so as to switch the normal operating regime of the power source module to the safe regime. In the normal operating regime, its DC output has a high voltage, whereas in the safe regime the DC output has a low voltage lower than the high voltage. The safety channels each include a shutdown circuit and a discharging circuit. The shutdown circuit is operative to switch the DC/DC converter off. The discharging circuit is operative to discharge the output capacitor below to the desired. The switching off DC/DC converter and discharging of the output capacitor define the safe regime of the power source module. The laser safety control system further includes a high power fiber laser system and a laser pump system which receives the DC output from the power source and is prevented from radiating emission in the safe regime of the power source because in the safe regime the low voltage is insufficient for generation the laser emission.

摘要： A fiber laser device (1) emits pulsed output light. A control unit (70) instructs an amplification pumping light source (30) to emit amplification pumping light in a state in which seed light generation pumping light is emitted from a seed light generation pumping light source (10) and an optical switch (23) is changed to a transmission state. The control unit (70) changes the optical switch (23) from the transmission state to a non-transmission state, with the amplification pumping light being emitted from the amplification pumping light source (30). When seed light is emitted, the control unit (70) changes the optical switch (23) to the transmission state again. The control unit (70) controls a period for which the optical switch (23) is in the non-transmission state and controls the intensity of the amplification pumping light emitted from the amplification pumping light source (30).
