We report over a superior typical electricity and substantial repetition price nanosecond pulsed eye-safe KGW Raman laser intracavity driven by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Using advantages of the carefully picked two-composite-laser-crystal configuration, the carefully optimized gate-open up time of acousto-optic modulator and also the ingeniously made U-formed resonator, substantial ability and efficiency enhancements and also top-quality mode matching have already been enabled.
Going on to Tm:YAG, the narrative shifts a little bit. This laser crystal features a dominant emission line within the vicinity of two.0 µm, a range that is certainly also considered to be eye-safe. Nevertheless, it’s the special Houses affiliated with this particular wavelength that truly established Tm:YAG aside.
A LED-array-pumped Nd:YAG laser with optical conversion efficiency up to 20.2% is demonstrated by immediate aspect-pumping without having a coupling lens by using the economical pump plan.
To sum it up, the higher optical get of Yb:Er:glass as well as check here the spectacular electric power dealing with of Tm:YAG underline their respective strengths. These gain parameters present invaluable insights into their general performance, enabling scientists and engineers to pick out the most fitted laser crystal for their distinct needs.

Once we talk of Yb:Er:glass, we refer to a laser crystal that primarily operates in an eye fixed-safe spectral location of all around 1.five µm. This wavelength region doesn’t just surface beautiful about the area; it carries important implications for a big range of purposes.
The defining attribute of those lasers is their operational wavelength, which generally falls inside the one.four to two micrometers selection. This spectrum is usually generally known as the “eye-safe�?region a result of the unique way through which the human eye responds to those distinct wavelengths.
The large ability makes sure that the laser beams can vacation to considerable heights and still have plenty of intensity on return to provide reputable info.
Yb:Er:glass crystals have carved a unique specialized niche in distant sensing and LIDAR techniques. Their higher optical gain and emission wavelength in the attention-safe area make them a perfect prospect for this sort of apps.
Regardless of the variances, both of those Yb:Er:glass and Tm:YAG continue to Engage in important roles from the expanding realm of laser technological innovation.
We present an end-pumped continual-wave intra-cavity yellow Raman laser at 590 nm which has a sixty mm extended pure crystal SrWO4 and an intra-cavity LiB3O5 frequency doubling crystal. The highest output power…
