Spatiotemporal self-similar fiber laser [PDF]
Optica, 2019 In this Letter, we demonstrate, to the best of our knowledge, the first spatiotemporally mode-locked fiber laser with self-similar pulse evolution. The multimode fiber oscillator generates parabolic amplifier similaritons at 1030 nm with 90 mW average ...

Evaluation of a nanosecond dissipative soliton resonance fiber laser for multiphoton microscopy [PDF]
Scientific ReportsMultiphoton microscopy often relies on femtosecond lasers due to their high peak powers and short pulse durations. However, these systems (e.g., Ti:Sapphire) are expensive, complex, and require dispersion compensation to maintain pulse parameters in the ...

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 ...
