With the appearance of latest nonlinear components and single-frequency pump resources, There may be renewed curiosity in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is each amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.

We report on the femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) dependant on the Kerr-lens-mode-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 internal to some MgO:PPLN femtosecond OPO, We now have generated broadly tunable radiation across 5958�?117 nm working with swift static cavity hold off tuning, with a utmost power of 64 μW at 6791 nm, restricted because of the absorption in mirror substrates along with polarization-dependent intracavity losses.

crystals with ultrafast Yb-ion laser pump is proposed. The outcome variety a beneficial reference for the selection of elements

In the two the situations attained unit mobile parameters are very same, which demonstrates the accuracy of existing technique. The electronic band structures present the semiconducting conduct in both the cases. The density of states plot are also examined and talked about.

We report new experimental final results to the phase-matching Qualities of yellow coloration HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-ten.5910 μm variety. On top of that, we current new Sellmeier equations that provide a superior copy of the current experimental outcomes as well as the revealed data factors for next-harmonic generation of CO2 laser radiation at 9.

prompted oscillations in the idler wavelength of less than 200MHz in excess of 300s; the short-phrase security was less than 3MHz

Taxonomy, chemical bonding relations and nonlinear optical Qualities of noncentrosymmetric sulfide crystals

This re-creation has long been current and revised to includeimportant developments, principles and technologies that haveemerged since the publication of the very first edition.

stabilize and tune the OPO, from which the good etalon gave an improved overall performance. Temperature oscillations in the PPLN crystal

The strategy relies on group velocity matching among interacting waves Together with birefringent period matching. We'll describe broadband SHG traits with regards to beam propagation directions, spectral positions of resonance, powerful nonlinearities, spatial walk-offs involving interacting beams, and spectral check here bandwidths. The effects will demonstrate that the spectral bandwidths of the elemental wave permitted for broadband SHG to reach various countless nm. The corresponding SH spectral range spans from 1758.fifty eight to 4737.18 nm from the non-oxide crystals thought of With this research. These broadband SHG making use of short pulse trains can most likely be applied to frequency up-conversion imaging inside the mid-IR location, in data transmission, As well as in nonlinear optical signal processing.

The observed f -to- two file frequency beats, originating straight from the OPO, may be used for self-referencing and stage locking from the pump laser comb without having for supercontinuum era. With an average output power of �?thirty mW , this setup may be effective for several different spectroscopic programs while in the mid-IR.

One-stage sub-200 fs mid-infrared era from an optical parametric oscillator synchronously pumped by an erbium fiber laser

Tunable mid-IR radiation is received through 2nd harmonic era of tunable CO2-laser radiation using a CdGeAs2 crystal. Its angular tuning traits at the CO2- laser wavelength, angular acceptance angle and spectral acceptance are calculated.
