Optical parametric oscillator pumped at ~one µm with intracavity mid-IR distinction-frequency era in OPGaAs
A mode-locked tunable dye laser is produced that's synchronously pumped at substantial repetition costs through the doubled output of a manner-locked Nd:YAG laser. The dye laser supplies intense pulses of 35 psec period which might be extensively tunable, of near-rework-constrained bandwidth, and in time coincidence While using the pumping pulses.
A list of ~450 noncentrosymmetric sulfides has long been observed in reference to nonlinear optical properties. It's been located that over the aircraft from the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
.. [Display total abstract] third-harmonic era and parametric amplification with lower-frequency pumping in periodically poled Lively nonlinear crystals will also be investigated. The Examination is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Views of employing periodically poled Energetic nonlinear crystals in laser gadgets with self-frequency conversion are discussed.
With this operate, we present what's, to our awareness, the 1st measurements of your quantum phase diffusion sounds of the cw OPO. Go through more
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including signal and idler, it could be continually tuned from 1.261 by 2.532 μm by different the pump wavelength. Two significant enhancements were reached, such as the connection with the signal and idler tuning ranges as well as large output pulse Strength from the sign and idler tuning ... [Show total summary] ranges. The primary enhancement was realized by finding two certain sets of stage-matching angles. The 2nd enhancement was understood by utilizing five sets of resonator mirrors for oscillating possibly signal or idler.
Taxonomy, chemical bonding relations and nonlinear optical Qualities of noncentrosymmetric sulfide crystals
We current a numerical review for the design of successful MgO:PPLN based mostly pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of leading-hat transverse depth profile, and a double-pass pump cavity configuration. In particular, we investigate the result of area condition over the conversion effectiveness. We regarded two types of area buildings: "ideal vertical-wall" and "wedge-shaped" domains and our numerical outcomes exhibit that at greater pump pulse energies, the conversion efficiency saturates, as well as the saturated efficiency is sort of unbiased from the domain shapes.
Additionally, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and discovered the spectral profile with the output from the CPOPO was appropriate to equally the parametric achieve profile in the nonlinear crystal as well as the intra-cavity large-order dispersion.
The technology of growing mercury thiogallate crystals (HgGa2S4) is enhanced and superior-excellent bulk samples are developed. The basic optical and thermal Attributes of those crystals are researched. The transmission spectra of mercury thiogallate are calculated and its nonlinear features such as the quadratic susceptibility, tuning curves, and the optical-destruction resistance are decided.
The approach relies on team velocity matching among interacting waves Besides birefringent phase matching. We'll describe broadband SHG attributes with click here regards to beam propagation directions, spectral positions of resonance, effective nonlinearities, spatial stroll-offs amongst interacting beams, and spectral bandwidths. The outcomes will display that the spectral bandwidths of the fundamental wave permitted for broadband SHG to achieve several many nm. The corresponding SH spectral range spans from 1758.fifty eight to 4737.eighteen nm during the non-oxide crystals viewed as On this review. These types of broadband SHG employing limited pulse trains can most likely be applied to frequency up-conversion imaging while in the mid-IR location, in details transmission, and in nonlinear optical signal processing.

One-action sub-200 fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Big difference frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams had been centered In the crystal without the need of hurt. Mixing of cw and pulsed laser methods was used to attenuate the thermal lensing outcomes inside this crystal. A very low-ability cw one.064‐μm Nd:YAG laser beam was utilized because the pump, Whilst the sign beam came from the picosecond optical .
