Abstract: Techniques are provided for controlling an output laser pulse signal of a medical device. A control device defines a time duration of capacitive discharge to a laser device. The time duration corresponds to an intended energy of the output laser pulse signal. The control device generates a plurality of sub-pulse control signals. The sub-pulse control signals define a series of capacitive discharge events of the capacitor bank. The control device modulates one or more of a sub-pulse control signal period or a sub-pulse time duration of the sub-pulse control signals to modify the capacitive discharge of the capacitor bank to the laser device during the time duration.

Abstract: The light source contains a gas-filled chamber with a plasma sustained by a focused beam of a continuous wave laser. The means for plasma ignition is a solid-state laser system which generates two pulsed laser beams: in a free running mode and in a Q-switched mode. The solid-state laser system contains single active element and its optical cavity is equipped with a Q-switch overlapping only part of a cross section of the intracavity laser beam. One pulsed laser beam provides an optical breakdown after which another pulsed laser beam ignites the plasma, the volume and density of which are sufficient for stationary sustenance of the plasma by the focused beam of the continuous wave laser. EFFECT: simplification of the design of the light source, increase of its reliability and ease of use, creating on this basis of powerful electrode-free high-brightness broadband light sources with high spatial and energy stability.

Abstract: Using a laser source unit, pulse laser beams having a plurality of wavelengths is switched and emitted. A Q switch is inserted into an optical resonator including a pair of mirrors which face each other with a laser rod interposed therebetween. A wavelength selection unit includes a plurality of band pass filters having different transmission wavelengths, and selectively inserts the plurality of band pass filters into a light path of the optical resonator. A trigger control circuit controls driving unit that drives the wavelength selection unit so that the band pass filters inserted into the light path of the optical resonator are switched at a predetermined switching speed. In addition, the trigger control circuit causes the laser rod to be irradiated with excitation light from a flash lamp, and then turns on the Q switch at a timing when the wavelength selection unit inserts the band pass filter.

Abstract: A slab laser and its method of use for high power applications including the manufacture of semiconductors and deposition of diamond and/or diamond-like-carbon layers, among other materials. A lamp driven slab design with a face-to-face beam propagation scheme and an end reflection that redirects the amplified radiation back out the same input surface is utilized. A side-to-side amplifier configuration permitting very high average and peak powers having scalability is also disclosed. Cavity filters adjacent to pump lamps convert the normally unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser, thereby increasing the overall pump efficiency. The angle of the end reflecting surface is changed to cause the exit beam to be at a different angle than the inlet beam, thereby eliminating the costly need to separate the beams external to the laser with the subsequent loss of power.

Abstract: This disclosure demonstrates successfully using single, polycrystalline, hot pressed ceramic, and thin film Fe doped binary chalcogenides (such as ZnSe and ZnS) as saturable absorbing passive Q-switches. The method of producing polycrystalline ZnSe(S) yields fairly uniform distribution of dopant, large coefficients of absorption (5-50 cm−1) and low passive losses while being highly cost effective and easy to reproduce. Using these Fe2+:ZnSe crystals, stable Q-switched output was achieved with a low threshold and the best cavity configuration yielded 13 mJ/pulse single mode Q-switched output and 85 mJ in a multipulse regime.
