Sum-frequency generation (SFG) of >16 W of 589 nm light has been achieved by a single pass through a 20 mm long, undoped, periodically poled, nearly stoichiometric lithium tantalate (PPSLT) crystal. This, to our knowledge, represents the highest repo

An analysis of the single point reproducibility of TD-THz based paint thickness measurements demonstrated a precision of 130 nm, corresponding to 0.1% of the measured thickness. A detailed model of the anticipated TD-THz waveforms from samples of var

Species mole fractions in a mixture of hydrocarbons were measured with an accuracy of better than 2% using a fast-sweeping, widely-tunable spectrometer based on difference-frequency generation in periodically poled lithium niobate waveguides.

The suitability of time-domain THz methods for non-contact measurements of marine paint thickness was investigated. Under laboratory conditions a 95% confidence interval of 120 nm was observed when a 134 μm thick film was measured.

We report on the first successful installation of a commercial solid-state sodium guidestar laser system (GLS). The GLS developed at LMCT was delivered to Gemini North Observatory in February of 2005. The laser is a single beacon system that implemen

We have demonstrated 3.5W of 589nm light from a fiber laser using periodically poled stoichio-metric Lithium Tantalate (PPSLT) as the frequency conversion crystal. The system employs 938nm and 1583nm fiber lasers, which were sum-frequency mixed in PP

Stoichiometric lithium tantalate (SLT) has been identified as a promising alternative to congruent lithium niobate as substrate material for quasi-phasematched (QPM) nonlinear optical frequency conversion. The advantages of SLT include superior resis

Periodically poled, nearly-stoichiometric lithium tantalate has used to generate visible radiation (by second-harmonic generation using Nd:YAG laser) and mid-infrared radiation (by difference-frequency generation using a Nd:YAG laser and a tunable te
