Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR big difference-frequency generation in OPGaAs
It's got lengthy been predicted the section distinction between the signal and idler subharmonic outputs of an optical parametric oscillator (OPO) undergoes a random stroll method, similar to the section diffusion of the laser [1].
crystals with ultrafast Yb-ion laser pump is proposed. The outcome kind a valuable reference for the choice of elements
By utilizing intracavity dispersion Manage, near-change-minimal sign pulses of �?one hundred fs period with smooth one-peak spectrum are reached at 1264 nm, similar to an idler wavelength at 6440 nm. To the very best of our awareness, This can be The 1st time this sort of useful idler powers during the deep-IR are generated from a dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition fee.
We report new experimental effects to the period-matching Homes of yellow colour HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-10.5910 μm array. Also, we present new Sellmeier equations that provide a good copy in the present experimental outcomes and also the released info points for second-harmonic era of CO2 laser radiation at 9.
The calculated core level binding energies are in contrast with Individuals of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to become independent around the technological disorders of crystal progress. In distinction on the valence band spectrum, the distribution of electron states during the bandgap of HgGa2S4 crystals is identified to generally be strongly dependent on the technological problems of crystal advancement as shown via the photoluminescence Assessment.
The temperature dependence of refractive indices of optical elements is characterised During this function by what we connect with their normalized thermo-optic coefficients. They are decided experimentally by interferometric measurements of thermal enlargement and of variations in optical thickness at several laser wavelengths as operate of temperature. A suitable vectorial formalism applied to these facts makes it possible for predicting the thermal evolution from the refractive index all around the useful number of transparency.
A method is created to solve the procedure of shortened equations describing parametric era inside a one particular-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals and the exceptional reflection coefficient on the output mirror are estimated versus the pump Strength density Wp at various values from the OPO nonstationarity .
Modeling and experimental analyze on period matching of second harmonic era in various colour Hg Ga two S 4 crystals are performed. Using the acknowledged Sellmeier equations, the dispersion relation with weighting proportionally to shorter-wavelength boundary with the crystal transparency band is proposed.
This paper reviews the new developments in crystal advancement and singly resonant optical parametric oscillators for the generation of large one pulse Electricity and average powers inside the mid-IR from 3 to ten μm.
... The initial knowledge on the refractive index of orange HGS revealed by Levine et al. [35] integrated only couple wavelengths from the obvious and around-IR equally as an illustration on the feasibility of the crystal for birefringent period-matching. The refractive indices for your orange stage have been measured and tabulated in between 0.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser procedure. By making use of a 300 μm prolonged magnesium-doped periodically poled LiNbO three crystal since the parametric attain medium and configuring the OPO like a chirped-pulse oscillator, we received mid-infrared emission having an instantaneous bandwidth covering 3084�?466 nm. This end result signifies, to the very best of our knowledge, the widest instantaneous bandwidth acquired from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous probable of chirped-pulse oscillation in scaling the instantaneous click here bandwidth of extremely-fast OPOs.
Single-move sub-200 fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Diode-pumped optical parametric oscillation continues to be demonstrated for The very first time to our understanding in just one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions absorb the 812-nm radiation to deliver 1084-nm laser oscillation.
