Abstract: Portable, lightweight, compact, eye-safe, battery-operated laser range finder and digital compass assembly, mountable onto a personal weapon or aiming device, to accurately measure distance, azimuth and elevation angle of a target and increase the accuracy and probability of the hit. The laser range finder and digital compass assembly has a laser transmitter for transmitting an output laser beam having a wavelength in the range of 1.0 to 1.1 microns, an OPO converter for converting the output laser beam to an eye-safe range between 1.5 and 2.

Abstract: A unique pulse forming network assembly designed for use with a laser flashlamp. The inventive assembly includes a planar printed circuit board (14) to which a plurality of electrical energy storage elements (L1, C1) are mounted. The energy storage elements (L1, C1) are mounted on one side of the primed circuit board (14) so that the electrical contacts thereof extend therethrough. The contacts are wave soldered to complete the assembly. In a specific embodiment, the planar mounting of the energy storage elements (L1, C1) is enabled by the substitution of a conventional relay (K1) with a field effect transistor (Q1). The FET selectively connects the energy storage elements (L1, C1) to an output terminal of the network to activate the flashlamp. In a more specific embodiment, at least one of the energy storage elements is a capacitor (C1) which is connected to the housing (16) by a flange (18).

Abstract: The impingement cooled laser apparatus including a laser rod (12) that is surrounded by an inner sleeve (24) and an outer sleeve (28). The space between the inner and outer sleeves (24, 28) forms a fluid channel. Coolant is introduced via input ports (32) and fills the fluid channel between the two sleeves. There are evenly distributed small jet holes (38) through the inner sleeve (24) to allow the coolant to spray through to the laser rod (12). After the coolant has impinged perpendicularly on the laser rod (12), it is drawn off through coolant outlet ports (36).
