.. [Show whole abstract] parametric oscillator. The two independently centered beams have been produced to overlap Within the crystal. The focusing parameters of The 2 beams had been regarding the same. The concentrating operate created by Boyd and Kleinman for tightly centered beams was prolonged to periodically poled crystals to be able to match the temperature-tuning curve. A 0.66%/W efficiency was obtained for the main difference frequency mixing method.

A mode-locked tunable dye laser continues to be made that's synchronously pumped at substantial repetition costs because of the doubled output of a manner-locked Nd:YAG laser. The dye laser presents extreme pulses of 35 psec period that are widely tunable, of in the vicinity of-change-constrained bandwidth, As well as in time coincidence With all the pumping pulses.

.. [Demonstrate comprehensive summary] 3rd-harmonic technology and parametric amplification with reduced-frequency pumping in periodically poled Lively nonlinear crystals are investigated. The analysis is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Views of employing periodically poled Energetic nonlinear crystals in laser products with self-frequency conversion are discussed.

On this do the job, we current what is, to our expertise, the first measurements of your quantum stage diffusion sounds of the cw OPO. Go through more

We present a numerical examine for the look of successful MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top rated-hat transverse depth profile, plus a double-go pump cavity configuration. In particular, we look into the outcome of area condition to the conversion performance. We more info regarded as two sorts of domain structures: "excellent vertical-wall" and "wedge-formed" domains and our numerical results clearly show that at increased pump pulse energies, the conversion effectiveness saturates, plus the saturated effectiveness is almost unbiased of the domain designs.

The particular warmth and thermal conductivity of HgGa2S4 are measured. It is concluded which the merged Attributes of HgGa2S4 crystals can provide for them a number one position Among the many components Employed in nonlinear-optical devices for mid-IR-frequency conversion.

This paper testimonials the recent developments in crystal advancement and singly resonant optical parametric oscillators with the era of substantial one pulse energy and common powers from the mid-IR from 3 to 10 μm.

... The initial facts within the refractive index of orange HGS published by Levine et al. [35] integrated only couple wavelengths within the seen and close to-IR just as an illustration of the feasibility of this crystal for birefringent section-matching. The refractive indices for your orange period had been calculated and tabulated between 0.
