Nonlinear optical techniques are now recognized as the most efficient means available to
generate laser radiation at wavelengths that are presently inaccessible via conventional …

Since the invention of the first laser 30 years ago, the frequency conversion of laser radiation
in nonlinear optical crystals has become an important technique widely used in quantum …

The author reports the stable generation of 0.2-W average power IR pulses around 3.2 mu m
from the KTP parametric oscillator pumped by the Nd: YAG laser at 1.064 mu m. In addition …

1. Background The majority of NLO materialscurrently used in devices are fabricated from
bulk single crystals. Opti-mum properties for optical quality, such as transpar-ency …

We have constructed a numerical model of seeded optical parametric oscillators that is
appropriate for nanosecond or longer pulsed operation. We have also experimentally …

Optical properties of high-quality flux-grown potassium titanyl phosphate (KTiOPO 4, KTP)
crystals were studied at 81 K in the spectral range of 0.2–2.4 THz by terahertz time-domain …

A high-energy and tunable mid-infrared source based on BaGa_4Se_7 crystal was
demonstrated by single-pass difference-frequency generation (DFG). Orthogonally polarized …

We have demonstrated a high-pulse-energy nanosecond mid-infrared optical parametric
oscillator (OPO) based on the nonlinear crystal BaGa 4 Se 7 pumped by 1.064 µm Nd: YAG …

Polarization methods, introduced in the 1800s, offered one of the earliest ways to examine
protein structure. Since then, many other structure-sensitive probes have been developed …

We have operated a CW triply resonant optical parametric oscillator (OPO) using a
periodically poled lithium niobate crystal pumped by a Nd: YAG laser at 1.06 µm and …
