In summary, we reached a 1485 nm eye-safe intra-cavity diamond cascaded Raman laser with high peak electricity and slim linewidth. Benefitting from the usage of composite crystal and in-band pumping and the good manner matching provided by the V-shaped folded cavity, the machine realized a mean output electric power of 2.
The battle of eye-safe laser crystals, Yb:Er:glass and Tm:YAG, just isn't a lot a fight as This is a complementary relationship. The two crystals provide special positive aspects, and their selection is determined by the desired software.
When eye-safe lasers have significantly improved the safety profile of laser technologies, it is important to remember that they are not entirely possibility-free of charge.

The principle of emission wavelengths lies within the quite Main of laser technological know-how, dictating several parameters which include penetration depth, energy density, and safety actions. It’s no coincidence that Yb:Er:glass and Tm:YAG, two outstanding laser crystals, are mentioned for their eye-safe wavelengths.
The unique crystalline construction of Tm:YAG endows it that has a significant harm threshold, enabling it to operate effectively under higher-ability functions.
Correspondingly, the beam radius of the fundamental laser within the diamond could be properly stored below 100 µm. The above mentioned final results reveal the V-formed folded cavity With this do the job has a great thermal steadiness, which can guarantee a superior performance, especially a substantial output electric power in the subsequent.
Nevertheless, warning really should always be exercised to prevent possible hazards connected with substantial electrical power amounts or extended publicity. As a result of their relationship of function and safety, eye-safe lasers have expanded the horizons of laser applications, producing prospects for safer plus more responsible use of this potent engineering.
As a result of oblique incidence with the beam on to the folding mirror M2, the convergence points of the beam in the tangential airplane (T) and sagittal airplane (S) are misaligned, leading to the astigmatism. The basic laser within the diamond includes a beam dimension of 72 µm×80 µm, which happens to be drastically lowered in comparison to that in the straight cavity case (∼one hundred twenty µm in our experiments, not supplied). This can favor the improvement of the fundamental laser electric power density over the diamond and so the advance in the Raman conversion efficiency.
Even so, The important thing to knowing the entire likely of these systems lies in complete know-how and cautious managing.
Make sure you consider refreshing the website page. If that does not operate, remember to Speak to assist so we could tackle the challenge.
Yb:Er:glass is often Employed in distance measurements, environmental checking, and protection applications on account of its high gain. Tm:YAG is fitted to higher-electric power applications like wind velocity measurements and atmospheric website reports.

This is certainly important in LIDAR devices, where by laser beams are projected onto a focus on plus the reflected gentle is analyzed to ascertain the gap.
Past these, the emission wavelength of Tm:YAG is additionally helpful in health-related applications, specifically in laser surgery.
