We report with a higher ordinary energy and significant repetition charge nanosecond pulsed eye-safe KGW Raman laser intracavity driven by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Having benefits of the cautiously chosen two-composite-laser-crystal configuration, the totally optimized gate-open time of acousto-optic modulator as well as the ingeniously designed U-formed resonator, substantial electrical power and effectiveness enhancements and also remarkable method matching are enabled.
Transferring on to Tm:YAG, the narrative shifts a little bit. This laser crystal incorporates a dominant emission line during the vicinity of 2.0 µm, a spread that may be also regarded as being eye-safe. Nonetheless, it’s the unique Qualities connected with this particular wavelength that truly established Tm:YAG aside.
A LED-array-pumped Nd:YAG laser with optical conversion effectiveness up to 20.two% is demonstrated by immediate facet-pumping with out a coupling lens by using the efficient pump plan.
Right use, adherence to safety protocols, normal routine maintenance, along with a healthier regard for the strength of lasers are all important in guaranteeing safe Procedure.
Subjects could be refined additional during the search engine results. The Topic side will reveal the superior-stage topics connected to the content returned inside the search engine results. Specific COLLECTIONS
However, warning should really usually be exercised to avoid probable dangers related to superior energy stages or extended publicity. As a result of their marriage of perform and safety, eye-safe lasers have expanded the horizons of laser programs, generating prospects for safer and more responsible use of this effective technology.
Equally, while in the medical discipline, these lasers have Increased the safety profile get more info of various techniques, allowing for Medical doctors to carry out fragile surgeries with considerably less chance on the affected person’s vision.
High typical electricity and higher repetition fee eye-safe Raman laser pushed by a two-crystal Nd:YVO4 laser
Eye-safe lasers have ushered in a whole new era in laser technologies by giving an unparalleled equilibrium concerning the strength of laser beams and safety issues. Their introduction has had much-achieving impacts across numerous domains, starting from telecommunications to defense, scientific research, and professional medical treatments. Essentially the most notable benefit of these lasers, certainly, lies within their safety profile.
In conclusion, while the emission wavelengths of Yb:Er:glass and Tm:YAG lead considerably for their eye-safe designation, it’s the large number of programs they empower and their exclusive properties that actually underline their worth in the field of laser technological innovation.
We proposed and experimentally demonstrated the generation of substantial-electric power 1176 nm Stokes wave by frequency shifting of the 885 nm diode-facet-pumped Nd:YAG laser employing a YVO4 crystal in a Z-shaped cavity…
Additionally, this exceptional energy handling capability also contributes towards the lengthy operational life and trustworthiness of Tm:YAG crystals.
Amongst the numerous characteristics of Yb:Er:glass is its large optical acquire. Basically, this means that a small enter of Power may lead to a significant output of laser light.
