Solid-Point out Laser Engineering is written from an industrialperspective and discusses in detail the properties, style, construction and sensible difficulties of strong-statelasers. Emphasis is put on engineering and practicalconsiderations, which has a phenomenological treatment usingmodelsbeing desired to abstract mathematical derivations.
The significance on the received benefits lies in The reality that to obtain the similar conversion in SHG or DFM, a single now calls for elementary input radiation with much lower intensity.
Aside from the compactness and benign running capabilities, it absolutely was the enormous overall flexibility in structure and output traits that led on the results of solid-point out lasers over the past forty decades.
An easy strategy for lessening the loss that is because of depolarization resulting from thermally induced anxiety birefringence in good-state lasers is claimed. The strategy employs only one intracavity quarter-wave plate with its rapid or sluggish axis aligned parallel to the preferred aircraft of polarization, outlined by an intracavity polarizer.
We report new experimental outcomes to the period-matching Qualities of yellow coloration HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-10.5910 μm selection. Furthermore, we current new Sellmeier equations that offer a excellent replica in the existing experimental final results in addition to the posted facts factors for 2nd-harmonic era of CO2 laser radiation at 9.
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Like sign and idler, it may be consistently tuned from 1.261 by way of two.532 μm by varying the pump wavelength. Two main advancements were being obtained, including the link of the signal and idler tuning ranges plus the high output pulse Vitality throughout the signal and idler tuning ... [Present total abstract] ranges. The primary enhancement was realized by identifying two unique sets of period-matching angles. The next improvement was realized by utilizing five sets of resonator mirrors for oscillating both signal or idler.

A method is developed to unravel the procedure of shortened equations describing parametric technology in the one particular-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals and the exceptional reflection coefficient on the output mirror are estimated compared to the pump Power density Wp at distinctive values with the OPO nonstationarity .
Furthermore, we executed a numerical simulation of chirped-pulse OPOs (CPOPOs) and unveiled that the spectral profile with the output from the CPOPO was pertinent to each the parametric get profile in the nonlinear crystal and the intra-cavity substantial-order dispersion.
The third harmonic of CO2-laser radiation has actually been acquired by passing the laser beam by means of two CdGeAs2 crystals in tandem, with the main crystal oriented for second-harmonic generation and the second for sum mixing. Employing This method, Now we have achieved an average external conversion efficiency of 1.
The strategy is based on team velocity matching concerning interacting waves Along with birefringent phase matching. We will explain broadband SHG features concerning beam propagation Instructions, spectral positions of resonance, productive nonlinearities, spatial stroll-offs among interacting beams, and spectral bandwidths. The effects will exhibit the spectral bandwidths of the elemental wave permitted for broadband SHG to reach quite a few many nm. The corresponding SH spectral assortment spans from 1758.fifty eight to 4737.18 nm in the non-oxide crystals viewed as On this analyze. These kinds of broadband SHG utilizing small pulse trains can probably be placed on frequency up-conversion imaging within the mid-IR area, in information and facts transmission, As well as in nonlinear optical signal processing.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser method. By making use of a 300 μm lengthy magnesium-doped periodically poled LiNbO three crystal as the parametric acquire medium and configuring the OPO being a chirped-pulse oscillator, we received mid-infrared emission possessing an instantaneous bandwidth masking 3084�?466 nm. This result signifies, to the ideal of our expertise, the widest instantaneous bandwidth received from a Yb-fiber-laser-pumped singly resonant OPO, click here demonstrating the enormous likely of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-rapidly OPOs.
On this paper we theoretically investigate essentially the most efficient pump temporal form for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Examination consists of fixing the exceptional Handle trouble using the fee equation formalism. The OPO exceptional buildup behavior is derived for just about any OPO configuration, and we clearly show which the optimum pump pulse form is usually a double rectangle. The very first rectangle is optimized to the buildup system, whilst the second one particular is optimized for that constant condition, and the two depend in a different way on the OPO mirror reflectivities as well as the obtainable pump Strength and greatest peak electrical power.
Tunable mid-IR radiation is acquired during 2nd harmonic generation of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning traits for the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
