We report with a large regular electricity 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. Having advantages of the meticulously picked two-composite-laser-crystal configuration, the extensively optimized gate-open up time of acousto-optic modulator plus the ingeniously developed U-formed resonator, substantial energy and efficiency enhancements and excellent mode matching happen to be enabled.
: Thulium-doped components are very effective, providing superior output power with nominal enter energy. Their operational wavelength ensures safety, making them well suited for apps like remote sensing and laser radar techniques.
A LED-array-pumped Nd:YAG laser with optical conversion performance up to 20.two% is demonstrated by immediate side-pumping without a coupling lens by utilizing the economical pump plan.
The efficiency and effectiveness of any laser process are mostly dictated by its gain parameters. The two Yb:Er:glass and Tm:YAG exhibit distinct traits in this element, Each individual leveraging its exceptional functions to jump out while in the broad spectrum of laser crystals.
Both equally crystals have their special strengths. The selection among The 2 depends on the particular application needs.
Once we talk of Yb:Er:glass, we seek advice from a laser crystal that generally operates in a watch-safe spectral area of around one.5 µm. This wavelength location doesn’t just appear attractive to the surface; it carries major implications for your big selection of programs.
Orthovanadate ErVO4 has been ready by reliable-period synthesis from the stoichiometric combination of significant pure V2O5 and chemically pure Er2O3 by multistage calcination in air in the temperature assortment…
Yb:Er:glass crystals have carved a unique niche in remote sensing and LIDAR techniques. Their significant optical attain and emission wavelength in the attention-safe region make them a super candidate for these purposes.
: Holmium-doped gain media present great effectiveness inside the clinical field because of their significant absorption coefficient in water. This permits for exact energy supply on the target tissue, cutting down the possible damage to encompassing spots.
A not-for-income organization, IEEE is the whole world's most significant specialized Experienced Firm devoted to advancing engineering for the good thing about humanity.
Even though eye-safe lasers are safer, poor managing can still more info pose dangers, for instance thermal injuries or accidental beam route into your eye.
