With the advent of latest nonlinear supplies and single-frequency pump resources, there is renewed fascination in optical parametric oscillators (OPOs). Only one-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly the two amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
We report with a femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) according to the Kerr-lens-method-locked Ti:sapphire laser as being the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO according to the nonlinear crystal, CdSiP two , synchronously pumped internal to the MgO:PPLN femtosecond OPO, We have now generated broadly tunable radiation across 5958�?117 nm working with swift static cavity delay tuning, having a most energy of 64 μW at 6791 nm, constrained by the absorption in mirror substrates and polarization-dependent intracavity losses.
The 1st-concepts density practical calculations are carried out to study the geometries and electronic constructions of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite constructions, along with the optical Attributes of all crystals are investigated systematically. The final results suggest that these compounds have identical band buildings along with the band gap decreases from S to Se to Te. For the linear optical Attributes, a few crystals demonstrate excellent mild transmission while in the IR and section obvious areas, and especially, HgGa2S4 and HgGa2Se4 crystals have average birefringence.
Scientific tests of feasible pump laser systems suited to ultrafast femtosecond OPOs based upon CdSiP two are reviewed, as well as the favorable linear and nonlinear optical properties, in addition to exceptional period-matching features of CdSiP two , are offered using The newest Sellmeier equations for the material. The explained experimental benefits signify the very best output pulse Vitality and report normal electric power in the ultrafast picosecond and femtosecond time click here scales throughout the 6–seven μm spectral range so far.
Self-referenced octave-wide subharmonic Hole optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
brought about oscillations inside the idler wavelength of fewer than 200MHz more than 300s; the small-term balance was below 3MHz
The era of tunable pico- and femtosecond light-weight pulses with parametric frequency conversion processes has attracted greater consideration recently1. New crystal supplies, as BBO, LBO, and KTP, with superior nonlinearity and substantial harm threshold are actually accessible, and pump lasers of enhanced stability enable the trustworthy Procedure of optical parametric oscillators. Parametric equipment pumped ... [Display comprehensive summary] either by cw modelocked lasers or by single intensive ultrashort pulses are already created. Within this contribution parametric systems are talked about which happen to be pumped by rigorous pulse trains of a few microseconds length and repetition prices as much as 50Hz.
We present a numerical review for the look of successful MgO:PPLN dependent pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top rated-hat transverse depth profile, as well as a double-pass pump cavity configuration. In particular, we look into the outcome of area form about the conversion effectiveness. We thought of two varieties of domain structures: "ideal vertical-wall" and "wedge-formed" domains and our numerical success exhibit that at bigger pump pulse energies, the conversion performance saturates, plus the saturated effectiveness is sort of independent in the domain styles.
The particular heat and thermal conductivity of HgGa2S4 are measured. It can be concluded that the blended Attributes of HgGa2S4 crystals can offer for them a number one posture One of the elements Utilized in nonlinear-optical products for mid-IR-frequency conversion.
The third harmonic of CO2-laser radiation has been acquired by passing the laser beam by way of two CdGeAs2 crystals in tandem, with the primary crystal oriented for next-harmonic generation and the 2nd for sum mixing. Using this technique, we have obtained a mean exterior conversion performance of one.
Interference is observed concerning the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
Note: Author names will likely be searched within the search phrases discipline, also, but that may obtain papers in which the individual is pointed out, instead of papers they authored.
An easy quantum model agrees nicely While using the experimental final results and makes it feasible to interpret the effect when it comes to
Diode-pumped optical parametric oscillation has actually been shown for the first time to our awareness in a single 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 generate 1084-nm laser oscillation.
