.. [Clearly show complete abstract] parametric oscillator. The two independently targeted beams had been designed to overlap In the crystal. The focusing parameters of The 2 beams ended up regarding the same. The focusing function designed by Boyd and Kleinman for tightly centered beams was extended to periodically poled crystals so as to in good shape the temperature-tuning curve. A 0.66%/W efficiency was obtained for the main difference frequency mixing approach.
We report with a femtosecond optical parametric oscillator (OPO) to the 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 based upon the nonlinear crystal, CdSiP 2 , synchronously pumped internal to some MgO:PPLN femtosecond OPO, We've generated broadly tunable radiation across 5958�?117 nm employing immediate static cavity hold off tuning, that has a maximum power of 64 μW at 6791 nm, limited through the absorption in mirror substrates along with polarization-dependent intracavity losses.
In addition to the compactness and benign running characteristics, it had been the enormous adaptability in design and style and output properties that led to the success of solid-point out lasers during the last forty several years.
A simple technique for reducing the reduction that is because of depolarization resulting from thermally induced tension birefringence in good-condition lasers is noted. The method makes use of a single intracavity quarter-wave plate with its quickly or slow axis aligned parallel to the preferred aircraft of polarization, outlined by an intracavity polarizer.
Self-referenced octave-wide subharmonic Hole optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
The calculated Main amount binding energies are as opposed with Those people of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to be unbiased over the technological disorders of crystal development. In distinction into the valence band spectrum, the distribution of electron states inside the bandgap of HgGa2S4 crystals is observed being strongly dependent upon the technological problems of crystal advancement as shown because of the photoluminescence Assessment.
Ultrafast femtosecond mode-locked fiber laser performs an indispensable function in professional medical imaging, House ranging, ophthalmology, terahertz spectroscopy, material micromachining, etc. It’s not only an important tool for persons to investigate the world, but additionally a pillar field of laser technological innovation. This evaluation current the technology of femtosecond pulses in ultrafast mode-locked fiber lasers working with Energetic, passive, hybrid method-locking methods, the emphasis is presented to passively method-locked fiber lasers. When it comes to the optimization of femtosecond pulses, we introduce the external compression system to obtain shorter pulse width, chirped pulse amplification strategy to extend pulse energy and procure significant Strength read more femtosecond pulses at the sensible band.
We existing a numerical review for the look of economical MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of prime-hat transverse intensity profile, along with a double-pass pump cavity configuration. Particularly, we investigate the influence of area shape around the conversion efficiency. We regarded as two types of domain structures: "perfect vertical-wall" and "wedge-shaped" domains and our numerical final results clearly show that at bigger pump pulse energies, the conversion efficiency saturates, along with the saturated effectiveness is sort of unbiased of the area shapes.
Moreover, we performed a numerical simulation of chirped-pulse OPOs (CPOPOs) and exposed that the spectral profile of the output from a CPOPO was pertinent to equally the parametric attain profile from the nonlinear crystal and the intra-cavity high-purchase dispersion.

... The main info within the refractive index of orange HGS posted by Levine et al. [35] integrated only number of wavelengths during the visible and around-IR just as an indication of your feasibility of the crystal for birefringent stage-matching. The refractive indices for that orange period were calculated and tabulated between 0.
