Abstract: The present invention relates to a system for modulating laser pulses by means of an electro-optical modulator which is operated by means of a pulsed modulation voltage. A voltage converter mounted upstream of the modulator converts a pulsed modulated switching voltage at an output voltage level to the modulation voltage that is higher than the output voltage level. The invention further relates to a method for modulating laser pulses.

Abstract: An optically stacked, laser diode array module (10) includes a mounting block (100) having a series of stepped, parallel diode mounting surfaces (101) on one face of the block, each diode mounting surface cooperating with a respective pair of reference surfaces (102, 103) of the block to form a respective outside block corner, a series of laser diodes (300) affixed to the block, with facets of the diode aligned with the reference surfaces forming the outside block corner with the mounting surface on which the diode is disposed, such that a corner of each diode is aligned with a respective corner of the block, and a beam reflector (200) secured to the block and having a series of stepped, parallel surfaces, each positioned to intercept and reflect a respective one of the beams (500) from the laser diodes, such that the reflected beams are parallel and stacked. The beams (500) emitted from the laser diodes (300) can be collimated by microlenses (400).

Abstract: A light generating apparatus is operably coupled to an optical fiber (10) with a cladding (5) and a core (4) defining a core diameter. The optical fiber (10) has a numerical aperture, and the product of the numerical aperture of the fiber and one-half the diameter of the core (4) is less than or substantially equal to 400 millimeter-milliradians. The apparatus includes a plurality (7) of laser diode arrays (6, 23, 55), each array comprising at least one light emitting region (1, 24) adapted for emitting light in a individual beam (21, 11). The plurality of laser diode arrays (6, 23, 55) are arranged such that light from the individual beams (21, 11) is combined in a combined beam, and the combined beam has a first far-field, half-angle divergence in a first direction and a first waist dimension in the first direction, and a second far-field, half-angle divergence in a second direction, substantially perpendicular to the first direction, and a second waist dimension in the second direction.
