Little Known Facts About HgGa2S4 Crystal.

.. [Show whole abstract] parametric oscillator. The two independently concentrated beams were being built to overlap Within the crystal. The focusing parameters of the two beams were being with regard to the similar. The concentrating function developed by Boyd and Kleinman for tightly targeted beams was prolonged to periodically poled crystals so as to in good shape the temperature-tuning curve. A 0.66%/W effectiveness was attained for the primary difference frequency mixing course of action.

We report on 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 based on the nonlinear crystal, CdSiP two , synchronously pumped inside to the MgO:PPLN femtosecond OPO, We've created broadly tunable radiation throughout 5958�?117 nm employing fast static cavity delay tuning, with a most energy of sixty four μW at 6791 nm, restricted through the absorption in mirror substrates and also polarization-dependent intracavity losses.

This method makes it possible for the Procedure of extensively tunable optical parametric oscillators2 (OPO) and subsequent variation frequency generators3 developing tunable pulses of high peak ability. The higher energy of the pump pulse trains has specified benefits with the operation of a synchronously pumped OPO, e.g., relaxed steadiness requirements, and also the probable to operate with large cavity losses (e.g. steel mirrors) enabling significant tuning ranges with only one set of mirrors and superior output-coupling variables for pulse shortening.

By utilizing intracavity dispersion Manage, in the vicinity of-rework-minimal signal pulses of �?100 fs period with sleek solitary-peak spectrum are attained at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the most effective of our awareness, This can be The 1st time these types of sensible idler powers within the deep-IR happen to be generated from a dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition level.

In addition, the coherent beam mix and divided pulse amplification procedure to more Enhance pulse Vitality are summarized. At the end of this evaluation, we present a detailed overview with the purposes of femtosecond pulses including the era of supercontinuum and tunable femtosecond pulses, and many simple applications. Several Views and investigate directions of femtosecond pulses can also be resolved.

triggered oscillations in the idler wavelength of under 200MHz in excess of 300s; the shorter-term stability was a lot less than 3MHz

The era of tunable pico- and femtosecond light pulses with parametric frequency conversion procedures has attracted enhanced consideration recently1. New crystal elements, as BBO, LBO, and KTP, with outstanding nonlinearity and large hurt threshold are actually offered, and pump lasers of enhanced balance allow the responsible operation of optical parametric oscillators. Parametric equipment pumped ... [Present comprehensive abstract] both by cw modelocked lasers or by solitary rigorous ultrashort pulses have already been made. In this particular contribution parametric units are reviewed that happen to be pumped by powerful pulse trains of a few microseconds length and repetition rates approximately 50Hz.

Pumping mid-IR optical parametric oscillators in close proximity to 1 μm is eye-catching for its simplicity and electrical power scaling ability. To this intention, huge bandgap non-oxide nonlinear crystals are desired.

The technological innovation of growing mercury thiogallate crystals (HgGa2S4) is enhanced and large-excellent bulk samples are generated. The fundamental optical and thermal properties of such crystals are studied. The transmission spectra of mercury thiogallate are measured and its nonlinear attributes including the quadratic susceptibility, tuning curves, plus the optical-harm resistance are decided.

... The initial data about the refractive index of orange HGS printed by Levine et al. [35] bundled only handful of wavelengths in the seen and around-IR just as an illustration with the feasibility of the crystal for birefringent phase-matching. The refractive indices for that orange section had been measured and tabulated involving 0.

The observed f -to- 2 file frequency beats, originating directly from the OPO, can be employed for self-referencing and phase locking in the pump laser comb with no need for supercontinuum technology. With a mean output electric power of �?thirty mW , this set up may be helpful for various spectroscopic apps from the mid-IR.

Within this paper we theoretically look into the most productive pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical Investigation consists of fixing the exceptional Handle challenge using the fee equation formalism. The OPO optimum buildup actions is derived for just about any OPO configuration, and we demonstrate that the best pump pulse condition can be a double rectangle. The 1st rectangle is optimized for that buildup approach, even though the 2nd one is optimized for your steady condition, and both equally rely differently within the OPO mirror reflectivities plus the obtainable pump Power and maximum peak power.

Diode-pumped optical parametric oscillation is shown for the first time to our expertise in just one get more info Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions soak up the 812-nm radiation to produce 1084-nm laser oscillation.
