With the appearance of recent nonlinear materials and single-frequency pump sources, There is certainly renewed curiosity in optical parametric oscillators (OPOs). A single-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is the two amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
We report on a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP two , synchronously pumped interior to the MgO:PPLN femtosecond OPO, we have generated broadly tunable radiation across 5958�?117 nm working with swift static cavity delay tuning, using a utmost power of 64 μW at 6791 nm, constrained because of the absorption in mirror substrates and also polarization-dependent intracavity losses.
A set of ~450 noncentrosymmetric sulfides has actually been observed in reference to nonlinear optical properties. It's been identified that within the aircraft of the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned into a rosette of two intersected ellipses of «acentricity».
A simple technique for minimizing the reduction that is due to depolarization ensuing from thermally induced strain birefringence in reliable-state lasers is claimed. The procedure works by using a single intracavity quarter-wave plate with its quick or gradual axis aligned parallel to the popular plane of polarization, defined by an intracavity polarizer.
Within this operate, we existing what is, to our information, the initial measurements in the quantum period diffusion sounds of a cw OPO. Read through much more
brought on oscillations in the idler wavelength of lower than 200MHz above 300s; the short-term stability was lower than 3MHz
The technology of tunable pico- and femtosecond light-weight pulses with parametric frequency conversion procedures has captivated amplified attention recently1. New crystal supplies, as BBO, LBO, and KTP, with outstanding nonlinearity and large injury threshold are actually obtainable, and pump lasers of improved stability enable the responsible Procedure of optical parametric oscillators. Parametric units pumped ... [Clearly show full summary] both by cw modelocked lasers or by solitary extreme ultrashort pulses happen to be created. In this contribution parametric methods are discussed which are pumped by rigorous pulse trains of some microseconds duration and repetition rates nearly 50Hz.
air hole and enthusiastic in sequence by a typical pump beam. The phase in the interference is determined by the phase shifts at a few frequencies.

Analysis of latest, promising wide-band-hole nonlinear crystals for the mid-IR is provided. We centered on ternary and quaternary chalcogenides and based on their Bodily and chemical properties, which As well as linear and nonlinear optical Houses, determine the effectiveness of crystal utilization in certain laser experiments. The correlation between the composition, construction and output parameters and also the trends in adjustments of the principle features such as band gap, nonlinear susceptibility, laser harm threshold, and so forth, are shown.
... The primary knowledge on the refractive index of orange HGS revealed by Levine et al. [35] involved only couple of wavelengths inside the seen and near-IR just as a demonstration on the feasibility of the crystal for birefringent section-matching. The refractive indices for the orange phase had been measured and tabulated amongst 0.
12 μm and explain all frequency conversion strategies recognized to this point with them together with long run potential programs. Keyword phrases: Ternary and quaternary semiconductors, defect chalcopyrites, solid options, nonlinear optical crystals, mid-infrared
A pulsed TEA CO2 laser was applied to research the result of pump radiation parameters (method construction, wavelength, and pulse duration), concentrating disorders, absorption coefficient, and temperature over the performance of conversion into the check here next harmonic and on angular dependences of stage matching in ZnGeP2 crystals. Great agreement betweeen experimental and theoretical success is noticed. Read through a lot more
3% rms about 12 h in fantastic beam high quality. The in close proximity to-IR signal pulses through the OPO have a Gaussian pulse length of �?19 ps , calculated at 1284 nm. We've investigated the temperature tuning features of the OPO and in comparison the info With all the theoretical calculations working with the most recent Sellmeier equations and thermo-optic coefficients to the crystal. To the most beneficial of our understanding, This can be the to start with picosecond OPO according to CSP working at MHz repetition rates.
