We report on the large typical power and superior repetition level 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 diligently chosen two-composite-laser-crystal configuration, the carefully optimized gate-open time of acousto-optic modulator as well as the ingeniously built U-formed resonator, significant energy and performance enhancements and also outstanding method matching happen to be enabled.
Like Yb:Er:glass, Tm:YAG doesn’t only depend upon its emission wavelength to shine. It's also noted for its significant thermal conductivity and very good mechanical Qualities, enabling it to face up to higher-power operations and performance reliably in an array of conditions.
For environmental monitoring, the emission wavelength of Yb:Er:glass arrives into play. As this wavelength coincides While using the minimal-absorption window in the environment, it enables the transmission of laser beams in excess of lengthy distances without the need of major absorption by atmospheric constituents. This residence is a must have in programs which include air high quality monitoring and atmospheric reports.
It’s essential to remember that the wavelength of 1.five µm is only one element of Yb:Er:glass. Coupled with other exceptional Houses for instance wide attain bandwidth, high quantum efficiency, and temperature stability, Yb:Er:glass exhibits outstanding overall performance in several purposes, both of those concerning effectiveness and safety.
This aspect of substantial optical acquire not just permits a sturdy functionality but also encourages efficiency. The considerably less energy necessary to make a strong laser beam, the more source-effective the laser process results in being.
Having said that, eye-safe lasers, by virtue in their safe operational wavelength, mainly negate this requirement. This simplification not only cuts down involved prices but will also permits a far more at ease and less obstructed user encounter, enhancing efficiency and efficiency in various apps.
The one.five µm wavelength area is particularly fascinating since it coincides Along with the bare minimum drinking water absorption in biological tissue. This attribute makes Yb:Er:glass a perfect option for biomedical programs, exactly where it’s required to limit opportunity tissue hurt.
Superior average electrical power and higher repetition charge eye-safe Raman laser pushed by a two-crystal Nd:YVO4 laser
In this article, we proposed a V-shaped folded cavity to accomplish efficient operation of an eye-safe intra-cavity diamond cascaded Raman laser. Within the just one hand, the thermal impact with the laser crystal was mitigated a result of the utilization of composite crystal As well as in-band pumping, and However, the method matching and cavity stability are promoted with the V-formed folded cavity. EYE SAFE LASER CRYSTAL Because of this, a median output ability of 2.2 W which has a diode to second-Stokes conversion efficiency of eight.one% continues to be efficiently attained. The heart beat width of the 2nd-Stokes laser was significantly lowered from sixty ns of the basic laser to one.one ns mainly because of the Raman pulse compression, which triggered a peak power of up to 40 kW.
A not-for-profit Corporation, IEEE is the entire world's most significant technical Qualified Firm dedicated to advancing technology for the good thing about humanity.
Though Yb:Er:glass delivers higher optical obtain and an eye-safe emission wavelength, Tm:YAG is much more suited for superior-electricity applications. From the realm of remote sensing and LIDAR purposes, the two crystals prove for being indispensable assets, making certain eye safety while also catering to varied specific necessities.
It’s vital that you take into account that the wavelength of 1.5 µm is only one element of Yb:Er:glass. Combined with other exceptional Attributes for example wide acquire bandwidth, substantial quantum performance, and temperature stability, Yb:Er:glass reveals remarkable overall efficiency in several applications, the two with regard to performance and safety.
The use of eye-safe lasers in medical treatments, specifically those involving the eyes, has actually been revolutionary. These lasers have Increased the safety of delicate surgical procedures, which makes it feasible to carry out intricate functions with substantially reduced challenges to individuals�?eyesight.
