Abstract: An M2 value beam profiling apparatus and method is described. The M2 value beam profiler comprises an optical axis defined by a focussing lens assembly and a detector, wherein the focussing lens acts to create an artificial waist within an optical field propagating along the optical axis. The beam profiler also comprises a multiple blade assembly having a first set of blades located at an artificial waist position and a second set of blades longitudinally separated along the optical axis from the artificial waist position. The multiple blade assembly therefore provides a means for selectively passing the blades through the location of the optical axis. Employing these measured widths allows for the M2 value of the optical field to be determined.

Abstract: A method and apparatus of detecting laser in a laser warning receiver is disclosed. A panoramic lens assembly utilized in cameras is combined with a laser detection focal plane. Incident laser light is refracted in the panoramic lens and made to illuminate a multiplicity of individual sensor elements. By determining the corresponding intensity of the laser light on the sensors, the angle of arrival resolutions superior to the element angular resolutions can be achieved. The combination of a panoramic lens with a laser detection focal plane provides a low cost laser warning for wrap around ground based situational awareness.

Abstract: A pulsed UV laser assembly includes a partial reflector or beam splitter that divides each fundamental pulse into two sub-pulses and directs one sub-pulse to one end of a Bragg grating and the other pulse to the other end of the Bragg grating (or another Bragg grating) such that both sub-pulses are stretched and receive opposing (positive and negative) frequency chirps. The two stretched sub-pulses are combined to generate sum frequency light having a narrower bandwidth than could be obtained by second-harmonic generation directly from the fundamental. UV wavelengths may be generated directly from the sum frequency light or from a harmonic conversion scheme incorporating the sum frequency light. The UV laser may further incorporate other bandwidth reducing schemes. The pulsed UV laser may be used in an inspection or metrology system.

Abstract: A wavelength monitor monitors wavelengths of laser beams emitted from a laser source and transmitted through a collimating lens. The wavelength monitor comprises an etalon that serves as an optical filter, and an optical detector. The etalon has a transmittance that is periodic with respect to a frequency, and is disposed such that a pair of collimated beams, emitted through a pair of emitting ports of the laser source and then transmitted through the collimating lens, is incident on the optical filter at symmetrically positive and negative angles. The optical detector receives the pair of collimated beams transmitted through the etalon, and detects the intensities of the pair of collimated beams.

Abstract: A lens array has structures in which light of each light-emitting element in plural rows that has been incident on first lens faces in plural rows on a first plate-shaped portion is totally reflected by a second prism surface.

The light of each light-emitting element transmitted to the second lens face side is emitted by the second lens faces towards a side of end faces of an optical transmission body, and monitor light of each light-emitting element reflected towards the third lens face side is emitted by the third lens faces towards a side of light-receiving elements.
