We report on a significant typical ability and high repetition amount nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Having benefits of the thoroughly selected two-composite-laser-crystal configuration, the carefully optimized gate-open up time of acousto-optic modulator plus the ingeniously developed U-formed resonator, significant electric power and performance enhancements along with outstanding manner matching have already been enabled.
The performance and success of any laser program are mainly dictated by its achieve parameters. Both equally Yb:Er:glass and Tm:YAG exhibit distinctive traits in this factor, each leveraging its exceptional options to stick out from the broad spectrum of laser crystals.
Another advantage of eye-safe lasers is their potential to minimize the necessity for protective equipment. Traditional lasers, because of their probable possibility to your eyes, necessitate the usage of particular protecting eyewear to shield the operator’s eyes from accidental publicity.
We report over a substantial ordinary energy and high repetition price nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Having benefits of the thoroughly picked two-composite-laser-crystal configuration, the totally optimized gate-open time of acousto-optic modulator and the ingeniously made U-shaped resonator, substantial energy and performance enhancements as well as remarkable mode matching happen to be enabled.
For illustration, the extended wavelengths of eye-safe lasers can cause damage to the cornea or even the lens because of absorption. For that reason, correct safety actions and pointers should really continue to be followed diligently when handling and operating these lasers.
Eye-safe lasers also possess important possible for future technological enhancements. Their inherent safety properties could permit the development of new applications that were previously untenable resulting from safety concerns.
Orthovanadate ErVO4 has long been organized by sound-phase synthesis from a stoichiometric combination of substantial pure V2O5 and chemically pure Er2O3 by multistage calcination in air within the temperature vary…
Having said that, The true secret to knowing the entire prospective of such technologies lies in complete knowledge and cautious handling.
The 1.5 µm wavelength region is particularly intriguing as it coincides Together with the least drinking water absorption in Organic tissue. This characteristic helps make Yb:Er:glass a great choice for biomedical purposes, where by it’s required to decrease possible tissue more info damage.
A not-for-revenue Group, IEEE is the world's major technological Expert Business dedicated to advancing know-how for the good thing about humanity.
Users may possibly neglect to make use of appropriate protecting equipment, or disregard safety protocols, expanding the chance of accidental exposure.

Although Yb:Er:glass provides superior optical obtain and a watch-safe emission wavelength, Tm:YAG is more fitted to higher-energy applications. From the realm of remote sensing and LIDAR purposes, both crystals demonstrate to be indispensable belongings, guaranteeing eye safety while also catering to varied specific specifications.
