Abstract: Apparatus is disclosed for aligning optical components. The apparatus comprises a light source providing an emission, an optical element for receiving the emission from the light source, and at least one of the light source and the optical element being mounted to a gimbal mount. Adjustment of the light source and/or the optical element mounted to the gimbal mount adjusts the angle of incidence of the emission from the light source on the optical element. This adjustment in turn aligns the optical components. A method is disclosed for aligning optical components. The method comprises generating an emission from a light source, adjusting a gimbal mount on at least one of the light source and an optical element, wherein the angle of incidence of the emission from the light source is adjusted on the optical element, and fixing in place the position of the gimbal mount on the light source and/or the optical element.

Abstract: A compact wavelength monitoring and control assembly (110) for a narrow band (i.e., laser) source is provided, comprising two narrow bandpass, wavelength selective transmission filter elements (130, 160) of Fabry-Perot structure through which two separate collimated beams from a laser source are directed onto two photodetectors (145, 175). A control circuit processes the simultaneously acquired signals from the two detectors (145, 175) as the las er wavelength is varied. The device functions as an optical wavelength discriminator in which the detectors (145, 175) convert optical energy to current (or voltage) for a feedback loop for controlling the laser source. A ny one of a large number of discrete, predetermined wavelengths may be chosen f or locking using the same device.

Abstract: A compact wavelength monitoring and control assembly (10) for a narrow band (i.e., laser) source (12) is provided comprising a narrow bandpass, waveleng th selective transmission filter element (18), of Fabry-Perot etalon structure (18), through which two collimated beams from a laser source (12) are direct ed onto two closely spaced photodetectors (22, 20). For wavelength stabilizatio n, the differential output of the two photodetectors (22, 20) is used in a feedback loop (28) to stabilize the wavelength of the laser source (12) to t he desired wavelength. Through the dependence of the wavelength transmission of the Fabry-Perot etalon (18) on angle and physical parameters (i.e., refracti ve index and thickness), a wavelength variation of the source (12) is converted into a transmission loss, which is different for the two photodetectors (22, 20), so that the wavelength change is detected by changes in the signals output from the two detectors (22, 20).
