In summary, we achieved a 1485 nm eye-safe intra-cavity diamond cascaded Raman laser with superior peak electrical power and slim linewidth. Benefitting from the usage of composite crystal and in-band pumping and The nice mode matching supplied by the V-formed folded cavity, the system reached a median output electric power of 2.

The substantial attain serves as the foundation for amplifying mild alerts, contributing to the greater rigorous and targeted output laser beam that Yb:Er:glass is known for.

Inside the landscape of distant sensing and LIDAR techniques, the pivotal role played by Yb:Er:glass and Tm:YAG crystals can not be overstated. Each and every, with its exceptional list of Attributes, contributes considerably on the advancement of those critical systems.

By using mirrors with specially created transmissions in a very diode close-pumped hemispherical cavity, laser oscillations except for 1580 nm have been suppressed and an Increased pulse functionality of an…

A comparison from the spectroscopic parameters of Raman-Lively vibronic modes in a variety of crystalline supplies that has a look at to using these crystals for stimulated Raman scattering (SRS) is…

Nevertheless, caution really should usually be exercised to stop opportunity hazards related to substantial ability degrees or prolonged exposure. Through their relationship of operate and safety, eye-safe lasers have expanded the horizons of laser applications, making opportunities for safer and more dependable use of the effective technological know-how.

Mainly because of the oblique incidence in the beam onto the folding mirror M2, the convergence factors on the beam within the tangential airplane (T) and sagittal plane (S) are misaligned, leading to the astigmatism. The elemental laser on the diamond includes a beam sizing of 72 µm×80 µm, here which can be drastically lowered when compared with that while in the straight cavity situation (∼120 µm within our experiments, not supplied). This will favor the enhancement of the fundamental laser energy density around the diamond and so the advance with the Raman conversion effectiveness.

The large electricity makes sure that the laser beams can journey to significant heights and still have more than enough intensity upon return to offer trustworthy facts.

The 1.5 µm wavelength region is especially fascinating as it coincides While using the least water absorption in Organic tissue. This characteristic will make Yb:Er:glass a perfect option for biomedical apps, where it’s required to lower possible tissue problems.

Relocating on to Tm:YAG, the narrative shifts a bit. This laser crystal contains a dominant emission line inside the vicinity of two.0 µm, a variety that is certainly also looked upon as eye-safe. Nevertheless, it’s the one of a kind Homes affiliated with this distinct wavelength that really set Tm:YAG apart.

We proposed and experimentally demonstrated the generation of higher-ability 1176 nm Stokes wave by frequency shifting of a 885 nm diode-side-pumped Nd:YAG laser using a YVO4 crystal inside of a Z-formed cavity…
