Abstract: A synthesizer including a controller configured to receive a first signal. A digital-to-analog converter (DAC) is coupled to the controller and is configured to generate a voltage bias based on the first signal. The voltage bias corresponds to a target resonant frequency. A semiconductor laser is coupled to the DAC and is configured to receive a second signal tone. The semiconductor laser generates a plurality of tone signals having octave multiples of a base sub-harmonic tone of the second signal tone.

Abstract: A light source, calibration device and method of calibrating an imaging device is disclose. The calibration device includes the light source which includes an ultraviolet light layer that, in operation, generates ultraviolet light, and a quantum dot layer that absorbs the ultraviolet light and, in response, generates radiation within the near infrared region at a selected intensity. The near infrared light is received at the selected intensity at the imaging device and a sensitivity of the imaging device is altered to detect the near infrared light at the selected intensity provided by the light source.

Abstract: A system includes a planar waveguide that includes an active gain medium configured to receive pump light from a pump source and amplify stimulated emission light. The planar waveguide has a fast axis and a slow axis and is configured to operate in single mode in the fast axis and multimode in the slow axis. The system also includes a hybrid spatial filter configured to receive the amplified stimulated emission light from the planar waveguide and output laser light. The hybrid spatial filter includes a physical slit having a narrower dimension corresponding to the slow axis of the planar waveguide. The physical slit is configured to reduce an intensity of the amplified stimulated emission light received from the planar waveguide. The hybrid spatial filter also includes a Volume Bragg Grating (VBG) configured to constrain an angle of the amplified stimulated emission light and enable compact geometry intra-cavity beam expanding/collimating optics.

Abstract: A method includes creating a gas flow in a gas cell and cooling a portion of the gas flow to create a thermally-induced temperature gradient in the gas flow. The method also includes directing at least one laser beam through at least a portion of the gas flow with the thermally-induced temperature gradient. The gas flow can be directed axially along a length of the gas cell or transverse to the length of the gas cell, and the at least one laser beam can be directed axially along the length of the gas cell through at least the portion of the gas flow. The gas flow may represent a first gas flow, and the method may further include creating a second gas flow in the gas cell and cooling a portion of the second gas flow to create a thermally-induced temperature gradient in the second gas flow.

Abstract: A detector apparatus is provided and includes a collector having access to a sample of a gaseous fluid and a tester coupled to and disposed remotely from the collector. The tester includes a test chamber into which a sample is directed from the collector, an excitation element to excite the sample in the test chamber and a spectrum analyzing device coupled to the test chamber to analyze the excited sample for evidence of a concentration of particles of interest in the gaseous fluid exceeding a threshold concentration. The threshold concentration is defined in accordance with a type of the particles of interest and a residence time of the sample.

Abstract: A method, apparatus and system for profiling a material composition of a volume is disclosed. A beam source directs a pulsed beam of electromagnetic energy from into the volume. A plurality of backscattered beams is received at a detector. The plurality of backscattered beams is generated from a plurality of depths within the volume in response to interactions of the directed pulsed beam at the plurality of depths. A processor performs range gating of the plurality of backscattered beams to obtain a depth profile of backscattered intensity within the volume and estimates a material composition at different depths of the volume from the generated depth profile.
