Bladder tumours are rare in children, with only 0.4% of cases occurring in the first 2 decades of life. Herein, a pediatric patient who underwent TUR-B with a holmium: yttrium-aluminum-garnet (Ho:YAG) laser is presented. Its histopathology was reported as urothelial papilloma.
We demonstrate sub-picosecond holmium-doped fiber laser mode-locked with a broadband carbon nanotube saturable absorber. Ultrashort pulse operation has been obtained for the wavelength range of 2030 – 2100 nm with output power up to 60 mW and repetition rate of 15.7 MHz. In te n s it y, 1 0 d B /d iv 212
We developed a new holmium-doped triple-clad fiber (Ho-3CF), reducing the clad diameter to improve overlap between pump and doped-core, holmium concentration reduce influence of ion clustering on laser efficiency. illustrate here performance this in oscillator configuration. The emission is centered at 2.12 m by Bragg grating, active pumped 1.94 m thulium-doped laser. slope effici...
The factors formation the efficiency and safety of urinary stone crushing using holmium thulium fiber lasers were selected, substantiated normalized. A multifactorial integral criterion urolithiasis treatment by laser lithotripsy was formed analyzed. Recommendations are given for use stones.
The reliability and lifetime demanded by spacebased applications of 2-micron solid state lasers are beyond the capability of currently available laser diode arrays. This paper provides the status of an ongoing technology advancement effort toward long-lifetime high power laser diode arrays suitable for pumping Thulium and Holmium based solid state lasers.
