EYE SAFE LASER CRYSTAL Secrets
EYE SAFE LASER CRYSTAL Secrets
Blog Article
An economical eye-safe laser resource at 1500 nm based on a novel Raman crystal BaTeMo2O9 (BTM) is shown for The 1st time. The laser resource was produced with a 3rd get Stokes shift at…
Also, this excellent electrical power handling skill also contributes towards the lengthy operational daily life and trustworthiness of Tm:YAG crystals.
We report on a significant average electric power and high repetition rate nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Using benefits of the diligently chosen two-composite-laser-crystal configuration, the completely optimized gate-open up time of acousto-optic modulator and also the ingeniously developed U-formed resonator, significant energy and performance enhancements and top-quality manner matching have already been enabled.
Relocating on to Tm:YAG, the narrative shifts marginally. This laser crystal features a dominant emission line from the vicinity of 2.0 µm, a range that is certainly also thought to be eye-safe. However, it’s the exclusive properties affiliated with this specific wavelength that truly set Tm:YAG aside.
The thought of emission wavelengths lies at the really Main of laser technology, dictating several parameters like penetration depth, ability density, and safety steps. It’s no coincidence that Yb:Er:glass and Tm:YAG, two notable laser crystals, are pointed out for his or her eye-safe wavelengths.
People that are unaware of this possibility could unintentionally expose on their own to hazardous laser radiation.
A comparison with the spectroscopic parameters of Raman-active vibronic modes in different crystalline elements with a perspective to the use of these crystals for stimulated Raman scattering (SRS) is…
The substantial get serves as the foundation for amplifying light indicators, contributing to the greater extreme and concentrated output laser beam that Yb:Er:glass is known for.
The 1.five µm wavelength location is particularly interesting as it coincides Together with the least drinking water absorption in Organic tissue. This characteristic makes Yb:Er:glass a perfect choice for biomedical applications, the place it’s essential to limit potential tissue injury.
Determine 2(b) shows the elemental laser beam radius on both the Nd:YVO4 as well as the diamond under distinctive thermal lens focal lengths. In the situation of the thermal lens using a focal duration as tiny as one hundred seventy mm, the cavity is ready to maintain a effectively-matched partnership involving the pump and the basic laser.
High average electrical power and large repetition charge eye-safe Raman laser driven by a two-crystal Nd:YVO4 laser
Whatever the differences, each Yb:Er:glass and Tm:YAG continue on to Participate in significant roles while in the growing realm of laser know-how.
Whilst eye-safe lasers are safer, inappropriate handling can however pose dangers, including thermal injuries or accidental beam way in to the eye.
That is a preview of subscription material, log in by way of an institution to examine entry. Obtain this article
Moreover, the precise absorption qualities of read more eye-safe lasers have been leveraged in clinical applications to focus on and deal with precise tissues without the need of harming the surrounding locations.
