Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency generation in OPGaAs
We report over a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) based upon the Kerr-lens-mode-locked Ti:sapphire laser as the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based on the nonlinear crystal, CdSiP two , synchronously pumped interior to some MgO:PPLN femtosecond OPO, We have now created broadly tunable radiation across 5958�?117 nm applying immediate static cavity delay tuning, that has a highest ability of 64 μW at 6791 nm, minimal via the absorption in mirror substrates in addition to polarization-dependent intracavity losses.

By implementing intracavity dispersion control, close to-completely transform-minimal sign pulses of �?100 fs period with sleek one-peak spectrum are achieved at 1264 nm, akin to an idler wavelength at 6440 nm. To the most beneficial of our knowledge, This really is the first time these useful idler powers while in the deep-IR have been produced from the dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition level.
OPO were being improved by optimizing pump beam waistline and OPO cavity duration. Both of those air-spaced and strong etalons have been tested to frequency
Within this Introduction We are going to supply a short overview of the essential milestones in the event of strong-condition lasers, examine the array of effectiveness parameters attainable Using these lasers, and mention big purposes.

Modeling and experimental research on section matching of second harmonic technology in various shade Hg Ga 2 S 4 crystals are performed. Utilizing the known Sellmeier equations, the dispersion relation with weighting proportionally to short-wavelength boundary from the crystal transparency band is proposed.
This paper evaluations the modern developments in crystal development and singly resonant optical parametric oscillators for that generation of higher solitary pulse Vitality and typical powers in the mid-IR from 3 to ten μm.
... The very first knowledge about the refractive index of orange HGS check here published by Levine et al. [35] incorporated only several wavelengths inside the obvious and in close proximity to-IR just as an illustration with the feasibility of this crystal for birefringent period-matching. The refractive indices for the orange period have been calculated and tabulated between 0.
Take note: Writer names will likely be searched while in the key terms subject, also, but which will come across papers the place the person is mentioned, as opposed to papers they authored.
Mid-IR second-order NLO crystal is indispensable during the frequency conversion purposes during the mid-IR area. In comparison with DUV and UV/Vis/in close proximity to-IR NLO crystals, functional mid-IR NLO crystals are somewhat exceptional, and plenty of of them remain on the stage of laboratory investigate. This chapter testimonials the current development on the mid-IR NLO crystals, which primarily includes increasing the classical mid-IR NLO crystals into huge high-high quality types or into quasi-stage-matching structures that happen to be suited to the laser gadgets by a variety of growth approaches and Discovering new prospective mid-IR NLO crystals by introducing new design and style and synthesis procedures.
