Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variation-frequency technology in OPGaAs
We report with a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) according to the Kerr-lens-manner-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 your MgO:PPLN femtosecond OPO, Now we have produced broadly tunable radiation throughout 5958�?117 nm utilizing speedy static cavity delay tuning, with a greatest electric power of 64 μW at 6791 nm, limited with the absorption in mirror substrates in addition to polarization-dependent intracavity losses.

In both equally the situations received unit mobile parameters are identical, which reveals the precision of present technique. The Digital band buildings display the semiconducting conduct in both equally the circumstances. The density of states plot are researched and reviewed.
Self-referenced octave-broad subharmonic Hole optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which includes sign and idler, it could be continuously tuned from one.261 via two.532 μm by different the pump wavelength. Two key improvements were obtained, such as the link of your signal and idler tuning ranges along with the large output pulse Strength in the sign and idler tuning ... [Clearly show whole summary] ranges. The main improvement was achieved by discovering two distinct sets of stage-matching angles. The 2nd improvement was recognized by utilizing 5 sets of resonator mirrors for oscillating both signal or idler.
The temperature dependence of refractive indices of optical components is characterized in this perform by what we simply call their normalized thermo-optic coefficients. These are definitely determined experimentally by means of interferometric measurements of thermal growth and of alterations in optical thickness at some laser wavelengths as functionality of temperature. An acceptable vectorial formalism placed on these details permits predicting the thermal evolution from the refractive index everywhere in the handy variety of transparency.
A method is produced to resolve the procedure of shortened equations describing parametric technology in a a single-frequency OPO cavity underneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals as well as the best reflection coefficient from the output mirror are estimated versus the pump Power density Wp at diverse values of your OPO nonstationarity .
Modeling and experimental examine on section matching of second harmonic era in various color Hg Ga two S four crystals are carried out. Using the recognised Sellmeier equations, the dispersion relation with weighting proportionally to limited-wavelength boundary of your crystal transparency band is proposed.

... The 1st information within the refractive index of orange HGS revealed by Levine et al. [35] integrated only handful of wavelengths during the obvious and near-IR just as a demonstration in the feasibility of this crystal for birefringent stage-matching. The refractive indices to the orange section have been calculated and tabulated among 0.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser process. By using a three hundred μm lengthy magnesium-doped periodically poled LiNbO 3 click here crystal as being the parametric attain medium and configuring the OPO as being a chirped-pulse oscillator, we acquired mid-infrared emission obtaining an instantaneous bandwidth masking 3084�?466 nm. This result represents, to the top of our awareness, the widest instantaneous bandwidth acquired from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the immense prospective of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-quick OPOs.
Mid-IR 2nd-order NLO crystal is indispensable in the frequency conversion purposes from the mid-IR area. In comparison with DUV and UV/Vis/in close proximity to-IR NLO crystals, functional mid-IR NLO crystals are comparatively uncommon, and a lot of of them remain with the stage of laboratory investigate. This chapter assessments the new development on the mid-IR NLO crystals, which generally involves expanding the classical mid-IR NLO crystals into significant substantial-top quality kinds or into quasi-phase-matching constructions which are well suited for the laser units by many development approaches and exploring new likely mid-IR NLO crystals by introducing new design and style and synthesis tactics.
Variance frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams were targeted inside the crystal with no problems. Mixing of cw and pulsed laser methods was employed to minimize the thermal lensing outcomes within this crystal. A minimal-electricity cw one.064‐μm Nd:YAG laser beam was utilised since the pump, whereas the sign beam arrived from a picosecond optical .
