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 Raman amplifier comprises a pumping light producing means (1) for producing pumping lights. The pumping lights are multiplexed with a signal light propagated through an optical fiber (2) so as to give the signal light a Raman gain. The means (1) is constituted of a semiconductor laser of Fabri-Perot, DFB, or DBR type and an MOPA (3). The center wavelengths of the pumping lights are different from each other, and the intervals between them are 6 nm to 35 nm. An optical repeater provided in an optical fiber transmission line (8) compensates the loss caused by the optical fiber transmission line (8) and includes the Raman amplifier (9) used for the compensation. A Raman amplification method for Raman-amplifying a signal light by sending the signal light and pumping lights having mutually different center wavelengths through an optical fiber serving as a Raman-amplification medium, in which the power of the pumping light having a shorter wavelength is higher.

摘要： A harmonic Q switch laser device and its control method for obtaining a stable laser pulse while protecting a nonlinear optical crystal used for a wavelength conversion are presented. In this laser device, in a pause period of a laser train, a Q switch which is turned on makes the laser oscillates spuriously and continuously, and prevents a gain from accumulating in a gain medium Before a generation of a laser pulse, the Q switch is turned off for a specified period to raise the laser gain, so that a pulse of a specified magnitude is generated from the first shot when turning on the Q switch.

摘要： Eine Stromversorgung für eine Laserblitzlampe (2) enthält einen schnellen Schalter (6) und eine Steuerung (10) welche die Amplitude jedes einzelnen Impulses mit vorgebbarer Modulationsfrequenz (Mf) und Modulationstiefe (M T ) moduliert. Hierdurch können bei unveränderter mittlerer Leistung der einzelnen Impulse höhere Spitzenleistungen erzielt werden, so daß bei der Materialbearbeitung die erforderlichen Schwellenwerte besser überschritten werden können. Auch wird durch die Amplitudenmodulation der einzelnen Impulse die Bildung eines unerwünschten, abschirmenden Plasmas oberhalb der Bearbeitungsstelle unterbunden.

摘要： A laser system for medical treatment is disclosed which comprises a pump, wherein the laser system is adapted to be operated in pulsed operation so that at least one laser pulse of a temporally limited pulse duration (Tp) is generated. The generated laser pulse irradiates some part of the human or animal body so that a two-dimensional laser spot S is located on the top layer of the irradiated part of the human or animal body. The pump power of the pump of the laser system is modulated in such a way that the cumulative energy E s (T p / 2) which is delivered by said laser pulse to said laser spot S during the first half of the pulse duration is less than 45% of the energy E s (T p ) which is delivered by said laser pulse to said laser spot S during the entire pulse duration T p .
