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...

OBJECTIVES To review the current literature on intracorporeal laser lithotripsy. METHODS We searched PubMed for relevant reports up to January 2012, using the keywords 'laser', 'lithotripsy' and 'intracorporeal'. RESULTS We studied 125 relevant reports of studies with various levels of evidence. Efficient lithotripsy depends on the laser variables (wavelength, pulse duration and pulse energ...

OBJECTIVE To evaluate the utility of the holmium laser for partial nephrectomy in a porcine model. METHODS Transperitoneal lower pole laparoscopic partial nephrectomy was performed in 5 farm pigs. All animals underwent a left-sided laparoscopic partial nephrectomy and were kept alive for 2 weeks (survival group). Subsequently, a right laparoscopic partial nephrectomy was performed (acute grou...

INTRODUCTION Transurethral resection of the prostate (TURP) is still considered the gold standard to treat benign prostatic hyperplasia (BPH). However, photoselective vaporization of the prostate (PVP) has gained widespread acceptance as an alternative option requiring preoperative patient selection. Four laser systems are currently in use: holmium, thulium, diode and GreenLight. MATERIALS AN...

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.
