The Raman gain coefficient of the barium tungstate crystal was calculated while in the 532 nm to 1064 nm spectral region. The experimentally obtained information were being fitted Together with the empirical equation, which can take…
In length measurement, By way of example, the substantial optical acquire of Yb:Er:glass permits the production of powerful laser beams that will travel lengthy distances without having considerable attenuation.
We report over a large typical ability and higher repetition price nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Getting advantages of the carefully chosen two-composite-laser-crystal configuration, the extensively optimized gate-open up time of acousto-optic modulator as well as the ingeniously developed U-shaped resonator, substantial electric power and performance enhancements in addition to remarkable manner matching happen to be enabled.
Be aware: Creator names will probably be searched from the key phrases discipline, also, but which will obtain papers the place the person is mentioned, as an alternative to papers they authored.
A LED-array-pumped Nd:YAG laser with optical conversion effectiveness up to 20.2% is shown by direct side-pumping with out a coupling lens by utilizing the economical pump scheme.
We report with a superior average electrical power and large repetition fee nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Having advantages of the meticulously selected two-composite-laser-crystal configuration, the completely optimized gate-open up time of acousto-optic modulator plus the ingeniously made U-shaped resonator, substantial electric power and effectiveness enhancements in addition to outstanding method matching have been enabled.
Both of those crystals have their exceptional strengths. The selection in between The 2 depends on the particular application specifications.
The high get serves as the foundation for amplifying light alerts, contributing to the greater intensive and targeted output laser beam that Yb:Er:glass is known for.
Notice: Author names will likely be searched while in the keyword phrases industry, also, but which will obtain papers in which the person is pointed out, as opposed to papers they authored.
This assures minimized hazard of retinal damage, providing a safer substitute for different apps. Beyond the safety factor, Thulium-doped attain media also jump out due to their large effectiveness.
In this article, we proposed a V-shaped folded cavity to obtain effective Procedure of a watch-safe intra-cavity diamond cascaded Raman laser. Within the a person hand, the thermal effect on the laser crystal was mitigated due to the utilization of composite crystal As well as in-band pumping, and Alternatively, the manner matching and cavity stability are promoted because of the V-shaped folded cavity. Therefore, an average output electrical power of two.2 W using a diode to next-Stokes conversion efficiency of 8.one% has been properly attained. The pulse width website of the second-Stokes laser was greatly lessened from 60 ns of the fundamental laser to 1.one ns mainly because of the Raman pulse compression, which led to a peak electrical power of up to forty kW.
That is a preview of subscription material, log in through an establishment to check obtain. Accessibility this article
We proposed and experimentally demonstrated the technology of superior-ability 1176 nm Stokes wave by frequency shifting of the 885 nm diode-facet-pumped Nd:YAG laser employing a YVO4 crystal inside of a Z-formed cavity…

One among the significant characteristics of Yb:Er:glass is its higher optical acquire. Basically, this means that a small enter of Power may lead to a big output of laser gentle.
