In summary, we realized a 1485 nm eye-safe intra-cavity diamond cascaded Raman laser with significant peak electrical power and narrow linewidth. Benefitting from the usage of composite crystal As well as in-band pumping and The nice mode matching supplied by the V-formed folded cavity, the device achieved an average output energy of two.
Moreover, this top-quality electrical power dealing with skill also contributes to your long operational everyday living and dependability of Tm:YAG crystals.
Both crystals have their exceptional strengths. The choice among The 2 relies on the specific software specifications.
Relocating on to Tm:YAG, the narrative shifts a little bit. This laser crystal contains a dominant emission line while in the vicinity of 2.0 µm, a variety that's also thought of as eye-safe. On the other hand, it’s the one of a kind Homes linked to this certain wavelength that really set Tm:YAG apart.
For environmental monitoring, the emission wavelength of Yb:Er:glass arrives into Participate in. As this wavelength coincides While using the reduced-absorption window in the ambiance, it allows the transmission of laser beams more than very long distances without substantial absorption by atmospheric constituents. This house is a must have in purposes like air top quality checking and atmospheric scientific studies.

Having said that, eye-safe lasers, by advantage of their safe operational wavelength, mainly negate this prerequisite. This simplification not just reduces involved costs but will also allows for a far more comfortable and fewer obstructed consumer practical experience, improving productiveness and effectiveness in various programs.
For instance, particular eye-safe lasers may cause damage towards the cornea or the lens, particularly In case the publicity is prolonged or maybe the laser ability is substantial.
Substantial typical ability and superior repetition fee eye-safe Raman laser pushed by a two-crystal Nd:YVO4 laser
The special crystalline composition of Tm:YAG endows it which has a higher damage threshold, enabling it to operate effectively under superior-electrical power functions.

Customers may possibly neglect to work with acceptable protective gear, or disregard safety protocols, rising the chance of accidental exposure.
When a laser beam interacts Together click here with the human eye, the character from the injury incurred is dependent significantly to the laser’s wavelength. Particular wavelengths are more quickly absorbed from the cornea or even the lens, while some penetrate more on the retina, the light-sensitive layer at the back of the eye.
One among the numerous attributes of Yb:Er:glass is its significant optical acquire. Effectively, Because of this a little enter of Vitality may lead to a significant output of laser gentle.
