Application of diode-laser-pumped difference-frequency generation to spectroscopic trace gas detection in the atmosphere
The application of diode-laser-pumped tunable IR sources to trace gas detection in air is discussed. The design and technology issues of CW tunable mid-infrared difference-frequency generation are addressed. Feasibility ...
Spectral and temporal characteristics of a subpicosecond krypton fluoride excimer laser (krypton fluoride, photon fluorescence)
Spectral and temporal characteristics of a subpicosecond KrF excimer laser are determined with the use of a one meter spectrometer, a single shot intensity autocorrelator, and a single shot phase sensitive autocorrelator. ...
Optical characterization of lithium niobate thin film waveguides sputtered on sapphire substrates
Thin films of lithium niobate on various oriented sapphire substrates were fabricated by the rf sputtering method. Polarized He-Ne laser light with a wavelength of 6328 A was successfully coupled into the optical waveguides ...
Generation of broad bandwidth UV pulses via sum frequency mixing
Focusing effects on phase front curvature are important in determining the band-width generated in the near vacuum ultraviolet by sum frequency mixing of ultrashort pulses. Noncollinear sum frequency mixing is utilized to ...
Development of a high power, ultrashort pulse laser system
This work focuses on the development of a new high power, ultrashort pulse dye laser system based on solid state Nd:YAG pump sources for a synchronously pumped dye laser and a series of dye amplifiers. This system will be ...
Mid-infrared laser absorption-based sensors for trace gas detection using difference-frequency generation
Real-time, compact, laser absorption-based sensors for trace gas detection have been developed. Difference-frequency generation in a periodically poled lithium niobate (PPLN) crystal pumped by two compact lasers, a ...
