Piezooptical coefficients of La3Ga5SiO14 and CaWO4 crystals: A merged optical interferometry and polarization-optical examine
Utilizing the “odd transit time�?approach as well as a Nd:LuVO4 crystal possessing a substantial emission cross-segment and a brief fluorescence lifetime as being the acquire medium, a LGS electro-optic Q-switched laser was constructed that has a repetition rate of 200 kHz, average output electric power of four.39 W and pulse width of 5.1 ns. These effects show that LGS can be utilized to be a significant repetition rate Q-switch and free of piezoelectric ringing effects a minimum of in a repetition level of 200 kHz and that it can provide a sensible Q-switched laser that has a tunable superior repetition level For most purposes, for instance elements processing, laser ranging, remote sensing, etc.
when the above mentioned light-weight propagates within an optically Lively crystal along the Z-way with size L and refractive index nx and ny along the X- and Y- directions, respectively, the polarization state can be expressed as:

Such as, it may be placed on LD Nd:YVO4 solid-condition laser pumped with superior regular energy and Electrical power in excess of 100W, with the best charge nearly 200KHZ, the highest output as many as 715w, the pulse width around 46ns, the continual output up to just about 10w, along with the optical destruction threshold is 9-ten times larger than that of LiNbO3 crystal. 1/2 wave voltage and one/four wave voltage are lower than that of precisely the same diameter BBO Pockels Cells, and the fabric and assembly Price tag are reduce than that of a similar diameter RTP Pockels Cells . Compared with DKDP Pockels Cells, They may be non-Remedy and also have excellent temperature balance. LGS Electro-optical Cells can be utilized in harsh environments and can accomplish perfectly in various apps.

In comparison with past claimed lasers with LGS as Q-switcher21, this present laser has some pros inside the repetition rates and pulse width which must be attributed to the shorter cavity length (185 mm) and decreased used electric voltage (3400 V). The shorter cavity established the shorter roundtrip time and shorter pulse width and was produced according to the “odd transit time�?layout which was proposed because of the theoretical Assessment around the optical Energetic and electro-optic outcomes. The limitation of superior repetition rates of the electro-optic Q-switched laser is the piezoelectric effect which would generate the “piezoelectric ring�? The LGS crystal has a little piezoelectric coefficient of six × 10−12 C/N, which indicates which the “piezoelectric ring�?outcome is negligible.

In addition to, the “piezoelectric ring�?influence is also influenced with the utilized electro-subject. During the existing experiments, we applied a LGS Q-switcher having an substantial component ratio (five:one) which decreases the utilized electro voltage of 3400 V decreased when compared to the earlier very best result in LGS Q-switched laser (3600 V)21. We feel that LGS crystal has terrific possible for software on the generation of high repetition amount laser radiation and could be Employed in increased energy lasers. In the even further, shortening the laser cavity and enlarging the element ratio need to be beneficial with the lasers with greater repetition costs and shorter pulse width that are favorable in lots of purposes for instance supplies processing.
By rotating the quarter wave plate, the electro-optic crystal with optical action can create electro-optic modulation similar to These crystals without having optical activity, which include KD*P29 and BBO36. When compared With all the “even transit time”thirty style, which happens to be described as follows: The sunshine propagates in the LGS crystal along the Z course and after that alongside the -Z way as a way to get rid of the influence of optical exercise within the laser cavity30, the present analyzed “odd transit time�?layout demands only the rotation of a quarter wave plate As a result simplifying the laser cavity configuration.
