Abstract: A solid-state laser source of tunable and narrow-bandwidth UV light is disclosed. The system utilizes a fiber amplifier in a resonant cavity. An acousto-optic or electro-optic modulator is incorporated into the cavity in such a way that the energy stored in the gain medium is efficiently extracted in the form of high-peak-power, short-duration pulses. In addition, narrow bandwidth and linearly polarized output are simultaneously achieved. The light from the cavity is converted into the ultraviolet by frequency tripling, quadrupling, and/or quintupling the infrared light. The narrow bandwidth, or relatively pure light, is preserved with intracavity filtering, and the high peak light powers increase the efficiency of the nonlinear crystals in the frequency conversion stage.

Abstract: A semiconductor laser structure for generating high frequency modulation of light intensity is disclosed. The apparatus comprises a seminconductor substrate, a semiconductor master laser and first and second semiconductor slave lasers fabricated adjacent to each other on the semiconductor substrate. Bias current applied to the master oscillator is modulated at a preselected frequency to cause the master laser to generate a plurality of optical frequency modulation sidebands. The first and second slave lasers, which are tuned to be close to the preselected first and second sidebands of the master laser, are injection-locked to the first and second preselected sidebands of the master laser.

Abstract: A novel eye-safe, long range laser pointer system for use in day or night conditions is described. The system uses a short pulse laser and a gated camera to detect the laser spot at long ranges in the presence of a strong solar background. The camera gate is synchronized with incident laser pulses using a separate large area, fast photodiode to detect the high peak power pulses. Alternately, gate synchronization using a GPS-disciplined clock can be used. Eye-safe systems operating in the near-UV or SWIR band are described.

Abstract: A method and device for reducing the timing jitter in a passive Q-switched Nd:YAG solid state laser by spatially selective bleaching a thin sheet of a saturable absorber of Cr+4:YAG from a direction orthogonal to the direction of laser emission where the Cr+4:YAG transmission increases 18% when the bleaching probe beam is a single laser diode bar. For steady state operation of a passive Q-switched laser, the pulse-to-pulse timing jitter showed a −12× reduction in standard deviation from 241 nsec for free running operation to 20 nsec with optical triggering.

Abstract: A technique for the efficient coupling of pump light into a fiber by injeng the light through the side of a fiber leaving the fiber ends accessible to input and output coupling. This technique relies on the fabrication of a groove or a micro-prism into the side of the fiber. The groove shape is adapted effective to the variables of light wavelength, orientation of the source and variables relating to fiber construction so as to allow the efficient injection of pump light. Light emerging from a laser diode or other suitable means for launching light placed on the opposite side of the fiber, and in proximity to the fiber wall, propagates laterally through the fiber and impinges on the sides of the groove. The vertical rays impinging on the grove facets are specularly reflected and directed along the horizontal fiber axis of the outer core. By employing a reflective coating on the groove, the reflectivity of the groove facets approach 100% for a wide range of incidence angles. In this manner one can launch external optical signals into an optical fiber.

Abstract: A solid-state laser source of tunable and narrow-bandwidth UV light is disclosed. The system relies on light from a diode laser that preferably generates light at infrared frequencies. The light from the seed diode laser is pulse amplified in a light amplifier, and converted into the ultraviolet by frequency tripling, quadrupling, or quintupling the infrared light. The narrow bandwidth, or relatively pure light, of the seed laser is preserved, and the pulse amplifier generates high peak light powers to increase the efficiency of the nonlinear crystals in the frequency conversion stage. Higher output powers may be obtained by adding a fiber amplifier to power amplify the pulsed laser light prior to conversion.
