We report over a superior typical electrical power and substantial repetition amount nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Using advantages of the meticulously picked two-composite-laser-crystal configuration, the extensively optimized gate-open time of acousto-optic modulator as well as the ingeniously intended U-shaped resonator, substantial ability and efficiency enhancements together with superior mode matching are enabled.
By utilizing mirrors with specially made transmissions inside a diode conclusion-pumped hemispherical cavity, laser oscillations apart from 1580 nm were suppressed and an Improved pulse general performance of the…
A LED-array-pumped Nd:YAG laser with optical conversion effectiveness up to 20.2% is demonstrated by immediate aspect-pumping and not using a coupling lens by utilizing the effective pump scheme.
To sum it up, the higher optical acquire of Yb:Er:glass as well as extraordinary electricity managing of Tm:YAG underline their respective strengths. These attain parameters supply invaluable insights into their general performance, making it possible for scientists and engineers to select the most suitable laser crystal for their precise desires.
This facet of substantial optical gain not merely permits a sturdy effectiveness but will also encourages effectiveness. The less Strength needed to more info produce a powerful laser beam, the more useful resource-successful the laser program turns into.
Eye-safe lasers also possess significant likely for upcoming technological developments. Their inherent safety qualities could enable the event of recent programs which were Formerly untenable because of safety fears.
The 1.5 µm wavelength area is especially interesting since it coincides Using the bare minimum water absorption in Organic tissue. This characteristic will make Yb:Er:glass a really perfect choice for biomedical apps, in which it’s required to reduce potential tissue harm.
This ensures reduced danger of retinal injury, presenting a safer choice for numerous apps. Outside of the safety component, Thulium-doped gain media also stick out because of their higher efficiency.
Yb:Er:glass crystals have carved a singular market in remote sensing and LIDAR systems. Their substantial optical acquire and emission wavelength in the attention-safe area make them an excellent applicant for this kind of apps.
A not-for-profit Business, IEEE is the world's largest specialized professional Corporation devoted to advancing engineering for the benefit of humanity.
Even though eye-safe lasers are safer, inappropriate dealing with can continue to pose hazards, which include thermal injuries or accidental beam path in the eye.
It’s crucial to keep in mind that the wavelength of one.5 µm is just one element of Yb:Er:glass. Coupled with other distinctive Houses including wide gain bandwidth, substantial quantum performance, and temperature stability, Yb:Er:glass reveals superb General effectiveness in lots of applications, both with regards to performance and safety.
Whilst Yb:Er:glass presents large optical acquire and a watch-safe emission wavelength, Tm:YAG is much more suited for significant-electricity applications. During the realm of remote sensing and LIDAR applications, both equally crystals show to get indispensable assets, ensuring eye safety even though also catering to numerous certain prerequisites.
