longitudinally in substantial aperture with thin crystal, Consequently it minimizes the thermal results. It can be an
Then numerous number of experiments were conducted on a sizable-aperture laser system to check this method and experimental final results exhibit which the amplification of TSRS is drastically suppressed because of the laser-induced damage array.
a Deuterium distribution in DKDP crystals developed from methods with various deuterium contents and supersaturation stages starting from 0.
transmission line, and the top matching resistance R is equal for the resistance from the
The measurements of the biggest of those websites as well as the sizing of KDP injury web pages scale around linearly with pulse period. Similarities of damage in really unique supplies factors to Houses of laser-induced injury that are content impartial and provides insight for the fundamental physics of laser-induced harm.
e., potassium or hydrogen) close by. Crystals made up of both equally the 270-nm absorption band along with the Fe3+ EPR spectra had been X-ray irradiated at room temperature and afterwards subjected to your number of thermal anneals around one hundred fifty°C. These treatments induced modifications in each the absorption band as well as EPR spectra, nevertheless the behaviors of your optical and EPR capabilities didn't correlate. This may be discussed if a part of the Fe ions occupy a internet site from the KDP crystals besides the K+ web page. We propose that the majority of the optical absorption while in the two hundred-to-300nm area is due to Fe ions substituting for phosphorus; i.e., (FeO4)two�?molecular units are current inside the KDP crystals and give increase to ultraviolet absorption.
In addition, the intensity from the strongest peak of these crystals decreases first, and reaches the minimal value though the mole percentage of your deuterium articles while in the crystal is about 74%. Following that, the intensity improves with the increase of the deuterium focus within the crystal.
high regular electric power software, it is necessary to employ two parts of identical crystal to
single manner. It truly is identified which the damage threshold of KDP solitary crystal depends on the laser irradiation route, polarization
Things such as mechanical deformation and temperature modifications result in phase mismatch in optical parametric amplification devices, impacting Electrical power steadiness. A period compensation technique by way of the linear electro-optic result can defeat this limitation. Period mismatch payment properties ended up simulated through the linear electro-optic impact in 70%-deuterated DKDP and ninety five%-deuterated DKDP. This process was placed on OPA methods to verify its feasibility.
Examination on section matching and compression of amplified chirped pulse for different deuteration degree DKDP crystals

It can be concluded that DKDP crystals larger than ninety% deuteration level might be used in extremely-short substantial power laser programs with compressed pulses broader than thirty fs. The disadvantage is that the acceptance angles are small, escalating The problem of engineering regulation.
Liu et al. identified that there was a linear romance between refractive index and deuteration degree of DKDP crystal, which DKDP Switch Crystal might grow to be a possible system to find out the deuterium content49. On the other hand, the entire higher than procedures measured the variation with the Bodily and chemical Qualities of crystals Using the deuterium content to ascertain the deuterium articles of DKDP crystals indirectly.
