in which n consists of nx and ny, the refractive indices together the X- and Y- directions as gentle propagates within an optically active crystal alongside the Z- route.
Piezooptical coefficients of La3Ga5SiO14 and CaWO4 crystals: A put together optical interferometry and polarization-optical analyze
Having an optically active langasite (LGS) crystal because the electro-optic Q-switch, we show an economical Q-switched laser that has a repetition amount of 200 kHz. Based upon the theoretical Examination in the conversation involving optical activity and electro-optic assets, the optical action of your crystal has no affect on the birefringence all through Q-switching In case the quarter wave plate used was rotated to align While using the polarization route. That has a Nd:LuVO4 crystal possessing a sizable emission cross-part and a brief fluorescence lifetime as being the gain medium, a stable LGS Q-switched laser was made with normal output power of 4.
Optical action is often considered to be the birefringence of suitable-handed and left-handed circularly polarized light-weight with refractive indices of nR and nL31, respectively, where nR and nL may be expressed as:
You happen to be downloading an entire-text furnished by the authors of the publication. A preview of the comprehensive-textual content is provided by Optica Publishing Team.
LGS crystal has an array of programs: Along with piezoelectric effect, optical rotation impact, its electro-optical result overall performance is additionally very top-quality, LGS Pockels Cells have significant repetition frequency, substantial part aperture, slender pulse width, large electric power, extremely-small temperature and various circumstances are well suited for LGS crystal EO Q -switch. We utilized the EO coefficient of γ eleven to help make LGS Pockels cells, and selected its larger element ratio to lessen the 50 %-wave voltage of LGS Electro-optical cells, which may be suited to the electro-optical tuning of all- Solid-point out laser with larger electrical power repetition fees.

Tungsten/molybdenum thin films for application as interdigital transducers on high temperature secure piezoelectric substrates La3Ga5SiO14 and Ca3TaGa3Si2O14
Apart from, the “piezoelectric ring�?result is likewise affected via the used electro-field. In the present experiments, we utilized a LGS Q-switcher with the big facet ratio (5:1) which decreases the used electro voltage of 3400 V lower compared to the earlier greatest lead to LGS Q-switched laser (3600 V)21. We believe that LGS crystal has fantastic potential for software into the technology of substantial repetition fee laser radiation and could be used in higher ability lasers. From the even more, shortening the laser cavity and enlarging the factor ratio needs to be beneficial to the lasers with greater repetition rates and shorter pulse width which happen to be favorable in lots of programs such as products processing.
By rotating the quarter wave plate, the electro-optic crystal with optical exercise can produce electro-optic modulation just like Those people crystals without any optical action, which include KD*P29 and BBO36. In contrast Together with the “even transit time”thirty design, which can be referred to as follows: The sunshine propagates from the LGS crystal together the Z direction after which alongside the -Z course so that you can get rid of the impact of optical action while in the laser cavity30, the current analyzed “odd transit time�?style and design necessitates just the rotation of 1 / 4 wave plate So simplifying the laser cavity configuration.
An electro-optically Q-switched significant-Electrical power Er:YAG laser with two polarizers is proposed. By utilizing two Al2O3 polarizing plates more info and also a LiNbO3 crystal with Brewster angle, the polarization efficiency is substantially enhanced. Due to this fact, 226 mJ pulse Electrical power with sixty two ns pulse width is reached at the repetition charge of three Hz, the corresponding peak electric power is 3.
8 kHz, and an average output electricity of 877 mW ended up generated. Contemplating the psyched-condition absorption around the laser photons with the Er:Lu2O3 crystal, we have simulated the dynamic process of self-pulsed era by fixing the speed equations numerically. The simulation outcomes are per The standard traits of a Q-switched laser.
