Comparison of Holmium:YAG and Thulium Fiber Lasers on the Risk of Laser Fiber Fracture [PDF]
Journal of Clinical Medicine, 2021 Objectives: To compare the risk of laser fiber fracture between Ho:YAG laser and Thulium Fiber Laser (TFL) with different laser fiber diameters, laser settings, and fiber bending radii. METHODS: Lengths of 200, 272, and 365 μm single use fibers were used with a 30 W Ho:YAG laser and a 50 W Super Pulsed TFL.

Durability of laser fibers [PDF]
World Journal of Urology, 1995 In 90 patients treated with laser prostatectomy using the Urolase (n = 50) or Ultraline (n = 40) laser fiber, the fiber-tip durability was investigated. In general the Urolase fiber tips were less damaged than the Ultraline fiber tips. At visual inspection, 62% of the Urolase fiber tips were graded as minimally damaged in comparison with 28% of the ...

Physical Review Letters, 2007 We investigate the effects of two-dimensional confinement on the lasing properties of a classical random laser system operating in the incoherent feedback (diffusive) regime. A suspension of 250 nm rutile (TiO2) particles in a rhodamine 6G solution was inserted into the hollow core of a photonic crystal fiber generating the first random fiber laser and
