In summary, we reached a 1485 nm eye-safe intra-cavity diamond cascaded Raman laser with higher peak ability and slender linewidth. Benefitting from the use of composite crystal and in-band pumping and the good mode matching supplied by the V-shaped folded cavity, the gadget accomplished an average output electric power of two.
Furthermore, this outstanding electric power managing ability also contributes to your extensive operational lifestyle and trustworthiness of Tm:YAG crystals.
That is essential in LIDAR programs, the place laser beams are projected onto a goal and also the mirrored gentle is analyzed to find out the space.
By using mirrors with specially made transmissions in a very diode end-pumped hemispherical cavity, laser oscillations except for 1580 nm were being suppressed and an Improved pulse performance of the…
Another benefit of eye-safe lasers is their potential to attenuate the prerequisite for protecting gear. Conventional lasers, because of their likely risk into the eyes, necessitate the use of unique protecting eyewear to shield the operator’s eyes from accidental publicity.
The distinctive crystalline composition of Tm:YAG endows it using a large problems threshold, enabling it to operate effectively underneath significant-ability functions.
A comparison on the spectroscopic parameters of Raman-active vibronic modes in numerous crystalline supplies having a check out to the use of these crystals for stimulated Raman scattering (SRS) is…
But, caution really should always be exercised to circumvent possible dangers connected with large electricity stages or extended exposure. As a result of their marriage of perform and safety, eye-safe lasers have expanded the horizons of laser apps, developing opportunities for safer and a lot more dependable use of the highly effective technologies.
Due to the oblique incidence of your beam on to the folding mirror M2, the convergence details with the beam during the tangential aircraft (T) and sagittal aircraft (S) are misaligned, causing the astigmatism. The basic laser on the diamond has a beam size of 72 µm×eighty µm, which happens to be drastically lowered as compared to that within the straight cavity case (∼one hundred twenty µm inside our experiments, not given). This will likely favor the improvement of the fundamental laser energy density about the diamond and therefore the development from the Raman conversion effectiveness.
Figure 2(b) reveals the fundamental laser beam radius on each the Nd:YVO4 and also the diamond below diverse thermal lens focal lengths. In the case of a thermal lens which check here has a focal duration as small as 170 mm, the cavity is in a position to take care of a effectively-matched marriage amongst the pump and the elemental laser.
The significant electric power makes sure that the laser beams can vacation to considerable heights and however have ample intensity upon return to deliver reputable facts.
Relocating on to Tm:YAG, the narrative shifts a little. This laser crystal includes a dominant emission line while in the vicinity of two.0 µm, a spread that is definitely also considered to be eye-safe. Nevertheless, it’s the special Homes related to this certain wavelength that actually established Tm:YAG aside.
Whilst Yb:Er:glass provides superior optical achieve and an eye-safe emission wavelength, Tm:YAG is a lot more suited to large-power apps. Inside the realm of distant sensing and LIDAR apps, both crystals establish to get indispensable assets, making certain eye safety while also catering to numerous particular prerequisites.

Further than these, the emission wavelength of Tm:YAG can be beneficial in healthcare purposes, especially in laser surgical procedure.
