A laser fiber for use in performing a medical laser treatment includes an optical fiber and a fiber tip. The optical fiber includes a terminating end surface at a distal end. The fiber tip is positioned at the distal end of the optical fiber and includes a transmissive portion and a spacer portion. Laser energy discharged from the terminating end surface of the optical fiber is transmitted through the transmissive portion. The spacer portion defines a distal terminating end of the fiber tip that is spaced a predetermined distance from the terminating end surface of the optical fiber. The predetermined distance is set for shock wave generation for calculus destruction at the distal terminating end of the fiber tip.

Surgical laser systems and laser lithotripsy techniques

A surgical laser system () includes a first laser source (A), a second laser source (B), a beam combiner () and a laser probe (). The first laser source is configured to output a first laser pulse train (A) comprising first laser pulses (). The second laser source is configured to output a second laser pulse train (B) comprising second laser pulses (). The beam combiner is configured to combine the first and second laser pulse trains and output a combined laser pulse train () 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.

A surgical laser system includes a laser generator, a laser probe, a stone analyzer, and a controller. The laser generator is configured to generate laser energy based on laser energy settings. The laser probe is configured to discharge the laser energy. The stone analyzer has an output relating to a characteristic of a targeted stone. The controller comprises at least one processor configured to determine the laser energy settings based on the output.

A system may include a stone analyzer, a controller, a laser generator, and a beam combiner. The stone analyzer may be configured to generate an output relating to a natural or resonance frequency of a kidney or bladder stone. The controller may be configured to determine the natural or resonance frequency of the stone based on the output from the stone analyzer, and match a resultant pulse repetition rate with the natural or resonance frequency. The laser generator may be configured to generate at least two laser pulse trains, with each laser pulse train including laser pulses at a pulse repetition rate. The beam combiner may be configured to combine the at least two laser pulse trains into a combined laser pulse train including laser pulses at the resultant pulse repetition rate.
