With the advent of new nonlinear elements and solitary-frequency pump sources, There's renewed desire in optical parametric oscillators (OPOs). An individual-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's both equally amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
We report over a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) based on the Kerr-lens-manner-locked Ti:sapphire laser as being the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO according to the nonlinear crystal, CdSiP two , synchronously pumped interior to your MgO:PPLN femtosecond OPO, We've got generated broadly tunable radiation across 5958�?117 nm applying speedy static cavity delay tuning, which has a greatest electric power of 64 μW at 6791 nm, minimal with the absorption in mirror substrates in addition to polarization-dependent intracavity losses.
crystals with ultrafast Yb-ion laser pump is proposed. The effects sort a valuable reference for the selection of components
Research of feasible pump laser technologies suitable for ultrafast femtosecond OPOs based on CdSiP 2 are discussed, as well as favorable linear and nonlinear optical Qualities, in addition to unique section-matching traits of CdSiP 2 , are offered employing the most recent Sellmeier equations for the material. The explained experimental outcomes represent the highest output pulse Vitality and history normal ability in the ultrafast picosecond and femtosecond time scales through the six–seven μm spectral selection to date.
OPO were being enhanced by optimizing pump beam waist and OPO cavity length. Both equally air-spaced and sound etalons have been examined to frequency
This double rectangle is quantitatively explained which is per prior results claimed during get more info the literature. Also, numerical simulations are accustomed to validate our analytical model on a doubly resonant OPO and demonstrate consistent effects. The numerical simulations also show that an optimal prime-hat temporal profile could give performances very near those obtained Together with the best double rectangle.
Taxonomy, chemical bonding relations and nonlinear optical Qualities of noncentrosymmetric sulfide crystals
Depending on the theories of section matching and suitable composition ratio, the influence of composition ratio on the frequency conversions of two kinds (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thought of corresponding sellmeier equations, period matching diagrams of second harmonic technology and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers had been calculated, and also satisfactory composition ratios with several compositions.

The technological know-how of increasing mercury thiogallate crystals (HgGa2S4) is improved and large-high quality bulk samples are generated. The basic optical and thermal Attributes of those crystals are analyzed. The transmission spectra of mercury thiogallate are calculated and its nonlinear qualities including the quadratic susceptibility, tuning curves, as well as optical-harm resistance will also be established.
... The first information on the refractive index of orange HGS printed by Levine et al. [35] included only couple wavelengths within the noticeable and around-IR just as an illustration of your feasibility of the crystal for birefringent period-matching. The refractive indices with the orange stage were measured and tabulated between 0.
The noticed file -to- two f frequency beats, originating directly from the OPO, can be employed for self-referencing and section locking of your pump laser comb with no need for supercontinuum generation. With a mean output electricity of �?30 mW , this setup could possibly be advantageous for many different spectroscopic applications during the mid-IR.
A straightforward quantum design agrees nicely with the experimental success and causes it to be achievable to interpret the outcome when it comes to
