Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR distinction-frequency generation in OPGaAs
Effects of thermal conductivity measurements are documented for a number of of the greater just lately produced nonlinear optical crystals. New or considerably revised values of thermal conductivity had been acquired in 6 components. Notable thermal conductivities calculated had been All those for AgGaS2 [0.014 W/(cm K) and 0.
Aside from the compactness and benign functioning attributes, it had been the enormous overall flexibility in structure and output attributes that led to the achievements of solid-condition lasers over the last 40 many years.
A straightforward system for reducing the loss that is due to depolarization resulting from thermally induced tension birefringence in strong-state lasers is noted. The approach employs an individual intracavity quarter-wave plate with its quickly or slow axis aligned parallel to the preferred airplane of polarization, outlined by an intracavity polarizer.
with the laser emission wavelength. The minimal calculated track record sign in the PA sensor (applying higher purity
PA Ref-mobile, which noticeably reduces themeasurement errors from the methane concentration in thecase of instability
The era of tunable pico- and femtosecond gentle pulses with parametric frequency conversion processes has attracted improved focus recently1. New crystal components, as BBO, LBO, and KTP, with outstanding nonlinearity and significant destruction threshold at the moment are out there, and pump lasers of enhanced security enable the reputable operation of optical parametric oscillators. Parametric gadgets pumped ... [Clearly show full abstract] either by cw modelocked lasers or by single intense ultrashort pulses happen to be created. Within this contribution parametric devices are discussed that are pumped by powerful pulse trains of a few microseconds duration and repetition rates nearly 50Hz.
Depending on the theories of stage matching and satisfactory composition ratio, the affect of composition ratio within the frequency conversions of two sorts (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In consideration of corresponding sellmeier equations, stage matching diagrams of second harmonic generation and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers were being calculated, together with suitable composition ratios with a variety of compositions.

The technological innovation of developing mercury thiogallate crystals (HgGa2S4) is improved and substantial-high quality bulk samples are generated. The essential optical and thermal properties of these crystals are researched. The transmission spectra of mercury thiogallate are measured and its nonlinear features including the quadratic susceptibility, tuning curves, as well as optical-destruction resistance are identified.
... The primary data around the refractive index of orange HGS released by Levine et al. [35] provided only handful of wavelengths inside the noticeable and in close proximity to-IR equally as an illustration on the feasibility of this crystal for birefringent stage-matching. The refractive indices with the orange stage have been measured and tabulated concerning 0.
twelve μm and describe all frequency conversion techniques understood to this point with them in addition to upcoming opportunity programs. Keywords: Ternary and quaternary semiconductors, defect chalcopyrites, reliable answers, nonlinear optical crystals, mid-infrared
During this paper we theoretically examine probably the most productive pump temporal form for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Investigation contains fixing the exceptional Handle problem utilizing the rate equation formalism. The OPO ideal buildup actions is derived for almost any OPO configuration, and we show that the optimal pump pulse form is really a double rectangle. The 1st rectangle is optimized to the buildup course of action, although the second 1 is optimized for your continuous state, and the two count differently around the OPO mirror reflectivities plus the accessible pump Strength and optimum peak electrical power.
Big difference frequency mixing of strongly targeted Gaussian beams in periodically poled LiNbO3 was investigated. The beams had been centered In the crystal without problems. Mixing of cw and pulsed more info laser devices was utilized to attenuate the thermal lensing results within this crystal. A very low-energy cw 1.064‐μm Nd:YAG laser beam was made use of as being the pump, Whilst the signal beam arrived from the picosecond optical .
