We report over a large typical energy and substantial repetition level nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Taking advantages of the cautiously chosen two-composite-laser-crystal configuration, the totally optimized gate-open up time of acousto-optic modulator and the ingeniously intended U-formed resonator, substantial ability and efficiency enhancements as well as excellent mode matching are already enabled.
Like Yb:Er:glass, Tm:YAG doesn’t entirely depend upon its emission wavelength to glow. It is additionally known for its high thermal conductivity and superior mechanical Attributes, enabling it to resist superior-electrical power functions and function reliably in an array of ailments.
Their special Qualities have not just paved just how for technological enhancements but have also unlocked new alternatives for long run exploration.

The two crystals have their exclusive strengths. The choice between The 2 depends upon the particular software specifications.
However, eye-safe lasers, by virtue in their safe operational wavelength, mainly negate this prerequisite. This simplification not just lessens linked charges and also permits a far more at ease and less obstructed person expertise, maximizing efficiency and performance in different applications.
One particular Principal application is wind velocity measurement. Higher-ability LIDAR programs working with Tm:YAG crystals can task laser beams to substantial altitudes to measure wind pace and path with amazing accuracy.
The superior power makes certain that the laser beams can travel to sizeable heights and nevertheless have plenty of depth upon return to deliver reliable info.
The substantial ability makes certain that the laser beams can journey to substantial heights and nonetheless have adequate depth upon return to provide responsible information.
Yb:Er:glass is often Employed in length measurements, environmental monitoring, and protection purposes due to its substantial obtain. Tm:YAG is fitted to high-electricity applications like wind velocity measurements and atmospheric scientific studies.
We proposed and experimentally demonstrated the generation of superior-electricity 1176 nm Stokes wave by frequency shifting of the 885 nm diode-facet-pumped Nd:YAG laser employing a YVO4 crystal within a Z-shaped cavity…
