Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency technology in OPGaAs
We report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) based on the Kerr-lens-method-locked Ti:sapphire laser as the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based upon the nonlinear crystal, CdSiP 2 , synchronously pumped inner to your MgO:PPLN femtosecond OPO, we have created broadly tunable radiation throughout 5958�?117 nm using fast static cavity delay tuning, using a greatest electricity of sixty four μW at 6791 nm, confined via the absorption in mirror substrates and polarization-dependent intracavity losses.
This technique lets the operation of greatly tunable optical parametric oscillators2 (OPO) and subsequent big difference frequency generators3 manufacturing tunable pulses of higher peak electricity. The upper Electrical power from the pump pulse trains has specified Advantages for the Procedure of the synchronously pumped OPO, e.g., comfortable steadiness specifications, as well as the probable to work with large cavity losses (e.g. metal mirrors) permitting big tuning ranges with only one set of mirrors and large output-coupling aspects for pulse shortening.
In the two the scenarios acquired device cell parameters are same, which reveals the precision of current strategy. The Digital band constructions display the semiconducting actions in both of those the cases. The density of states plot may also be analyzed and discussed.
In this particular perform, we present exactly what is, to our know-how, the first measurements of the quantum section diffusion noise of the cw OPO. Browse extra
In this Introduction We're going to offer a shorter overview on the vital milestones in the event of sound-point out lasers, discuss the range of general performance parameters doable Using these lasers, and mention big purposes.
The era of tunable pico- and femtosecond gentle pulses with parametric frequency conversion procedures has captivated increased interest recently1. New crystal supplies, as BBO, LBO, and KTP, with exceptional nonlinearity and higher harm threshold are now accessible, and pump lasers of enhanced steadiness enable the trustworthy operation of optical parametric oscillators. Parametric devices pumped ... [Show full summary] both by cw modelocked lasers or by solitary intensive ultrashort pulses are already designed. In this particular contribution parametric programs are talked about which can be pumped by extreme pulse trains of a few microseconds period and repetition premiums approximately 50Hz.
A technique is created to unravel the program of shortened equations describing parametric technology within a one-frequency OPO cavity under nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals and also the click here optimal reflection coefficient with the output mirror are estimated vs . the pump Strength density Wp at unique values in the OPO nonstationarity .
Modeling and experimental analyze on phase matching of 2nd harmonic technology in numerous colour Hg Ga 2 S four crystals are carried out. Using the recognised Sellmeier equations, the dispersion relation with weighting proportionally to brief-wavelength boundary with the crystal transparency band is proposed.
stabilize and tune the OPO, from which the solid etalon gave a better overall performance. Temperature oscillations within the PPLN crystal
Straightforward process for cutting down the depolarization reduction ensuing from thermally induced birefringence in stable-point out lasers
Note: Author names are going to be searched from the keyword phrases field, also, but that could come across papers in which the person is mentioned, as an alternative to papers they authored.
Solitary-stage sub-two hundred fs mid-infrared era from an optical parametric oscillator synchronously pumped by an erbium fiber laser
.. [Present whole summary] bandwidth. Experimental success demonstrating entanglement technology with higher fees as well as a comparison to your nicely investigated β-BaB2O4 (BBO) crystal are presented too. Switching the down-conversion crystal of the polarization entangled photon source from BBO to BiBO boosts the generation price as if the pump electricity was elevated by two.five moments. This kind of an advancement is at the moment essential for the era of multiphoton entangled states.
