Abstract

A surgical laser system (100) includes a first laser source (140A), a second laser source (140B), a beam combiner (142) and a laser probe (108). The first laser source is configured to output a first laser pulse train (144, 104A) comprising first laser pulses (146). The second laser source is configured to output a second laser pulse train (148, 104B) comprising second laser pulses (150). The beam combiner is configured to combine the first and second laser pulse trains and output a combined laser pulse train (152, 104) comprising the first and second laser pulses. The laser probe is optically coupled to an output of the beam combiner and is configured to discharge the combined laser pulse train.

Description

technical field [0001] Embodiments of the present invention generally relate to surgical laser systems, laser pulse sequences produced by such systems, and methods of performing laser lithotripsy using the systems and laser pulse sequences. Background technique [0002] Medical lasers are used in a variety of practical fields such as urology, neurology, ENT, general anesthesia, ophthalmology, dentistry, gastroenterology, cardiology, gynecology, chest surgery, and plastic procedures. Collectively, these procedures require precisely controlled delivery of laser energy as part of the treatment protocol. [0003] Lithotripsy for kidney and bladder stones is currently performed by ESWL (extracorporeal shock wave lithotripsy), surgery or using a laser (laser lithotripsy). In laser applications, a holmium-doped yttrium aluminum garnet (Ho: YAG) laser rod or a thulium-doped yttrium aluminum garnet (Tm: YAG) laser rod is used to generate laser energy with a wavelength of about 2000-...
