With the appearance of new nonlinear components and one-frequency pump resources, There is certainly renewed desire in optical parametric oscillators (OPOs). Only one-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's equally amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.

Final results of thermal conductivity measurements are reported for various of the more recently formulated nonlinear optical crystals. New or considerably revised values of thermal conductivity had been attained in six resources. Noteworthy thermal conductivities calculated ended up Those people for AgGaS2 [0.014 W/(cm K) and 0.

This method makes it possible for the operation of broadly tunable optical parametric oscillators2 (OPO) and subsequent difference frequency generators3 making tunable pulses of higher peak electric power. The upper Electricity with the pump pulse trains has specific Gains to the Procedure of a synchronously pumped OPO, e.g., relaxed security specifications, plus the possible to work with significant cavity losses (e.g. steel mirrors) enabling substantial tuning ranges with a single set of mirrors and significant output-coupling elements for pulse shortening.

The higher conversion efficiency and big selection of radiation wavelength tuning permits to anticipate that this product may possibly contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the significant difficulty of huge size crystals expansion method.

Self-referenced octave-broad subharmonic GaP optical parametric oscillator centered at three μm and pumped by an Er-fiber laser

brought on oscillations inside the idler wavelength of under 200MHz over 300s; the short-term stability was lower than 3MHz

The era of tunable pico- and femtosecond light pulses with parametric frequency conversion processes has captivated enhanced focus recently1. New crystal elements, as BBO, LBO, and KTP, with outstanding nonlinearity and substantial harm threshold are actually accessible, and pump lasers of enhanced steadiness enable the reputable operation of optical parametric oscillators. Parametric units pumped ... [Present total abstract] either by cw modelocked lasers or by single rigorous ultrashort pulses have been formulated. With this contribution parametric programs are talked about that are pumped by intensive pulse trains of a few microseconds duration and repetition fees up to 50Hz.

We existing a numerical review for the design of effective MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top rated-hat transverse intensity profile, as well as a double-move pump cavity configuration. Specifically, we look into the influence of area shape within the conversion efficiency. We viewed as two types of area structures: "fantastic vertical-wall" and "wedge-shaped" domains and our numerical results exhibit that at larger pump pulse energies, the conversion performance saturates, along with the saturated efficiency is nearly impartial from the domain styles.
