Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency generation in OPGaAs

We report with a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) based upon the Kerr-lens-mode-locked Ti:sapphire laser as being the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO dependant on the nonlinear crystal, CdSiP 2 , synchronously pumped inside to your MgO:PPLN femtosecond OPO, we have generated broadly tunable radiation throughout 5958�?117 nm using quick static cavity delay tuning, using a utmost electrical power of sixty four μW at 6791 nm, constrained via the absorption in mirror substrates together with polarization-dependent intracavity losses.

This system enables the Procedure of commonly tunable optical parametric oscillators2 (OPO) and subsequent change frequency generators3 producing tunable pulses of substantial peak electricity. The higher Strength on the pump pulse trains has specific Added benefits for your Procedure of a synchronously pumped OPO, e.g., peaceful balance demands, plus the likely to operate with substantial cavity losses (e.g. steel mirrors) making it possible for huge tuning ranges with just one list of mirrors and significant output-coupling variables for pulse shortening.

In each the situations attained unit cell parameters are very same, which reveals the accuracy of existing strategy. The electronic band constructions clearly show the semiconducting behavior in both of those the instances. The density of states plot may also be analyzed and reviewed.

Moreover, the coherent beam mixture and divided pulse amplification system to even more boost pulse Electricity are summarized. At the conclusion of this assessment, we present a detailed overview in the purposes of femtosecond pulses including the era of supercontinuum and tunable femtosecond pulses, and some functional purposes. Various perspectives and analysis directions of femtosecond pulses may also be dealt with.

brought about oscillations during the idler wavelength of less than 200MHz more than 300s; the brief-phrase stability was below 3MHz

While using an institutional account for this website we don’t keep track of any own, efficiency, practical or 1st or 3rd party related information.

We existing a numerical analyze for the look of efficient MgO:PPLN based mostly pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top-hat transverse depth profile, as well as a double-go pump cavity configuration. Specifically, we look into the effect of area shape about the conversion efficiency. We viewed as two types of area structures: "fantastic vertical-wall" and "wedge-shaped" domains and our numerical effects display that at greater pump pulse energies, the conversion efficiency saturates, and also the saturated effectiveness is almost impartial of the domain shapes.

Also, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and exposed which the spectral profile in the output from the CPOPO was appropriate to both equally the parametric get profile from the nonlinear crystal as well as intra-cavity large-purchase dispersion.

The 3rd harmonic of CO2-laser radiation has actually been acquired by passing the laser beam via two CdGeAs2 crystals in tandem, with the first crystal oriented for 2nd-harmonic generation and the next for sum mixing. Utilizing this technique, We have now reached a mean external conversion efficiency of 1.

Basic method for lessening the depolarization decline ensuing from thermally induced birefringence in stable-condition lasers

We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser process. By utilizing a 300 μm lengthy magnesium-doped periodically poled LiNbO 3 crystal as being the parametric get medium and configuring the OPO as a chirped-pulse oscillator, we obtained mid-infrared emission acquiring an instantaneous bandwidth masking 3084�?466 nm. This result signifies, to the most beneficial of our knowledge, the widest instantaneous bandwidth acquired from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the immense possible of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-rapidly OPOs.

A simple quantum model agrees perfectly While using the experimental effects and causes it to be feasible to interpret the influence with regards to

Big difference frequency mixing of strongly targeted Gaussian beams in periodically poled LiNbO3 was investigated. The beams have been targeted Within the crystal with out damage. Mixing of cw and pulsed laser systems was utilized to attenuate the more info thermal lensing results inside this crystal. A small-electric power cw 1.064‐μm Nd:YAG laser beam was used given that the pump, While the sign beam came from the picosecond optical .
