Problems solved by technology

However, the frequency of the holmium laser is low, the energy is high, the blasting force of the stone is strong, and the impact and displacement of the stone are serious. The time for the doctor to find the stone during the operation greatly delays the overall operation time.
The lamp pumping of the holmium laser has a short lifespan, which leads to the rapid attenuation of the output energy of the laser surgery equipment, often resulting in ineffective surgery
In addition, holmium laser and Tm:YAG laser have low electrical-to-optical conversion efficiency, large volume, high power consumption, and high noise, which seriously affect the doctor's intraoperative experience.

Description

technical field [0001] The invention relates to the technical field of laser detection equipment, in particular to a pulsed thulium fiber laser detection system and detection method. Background technique [0002] The application of laser technology in the medical field is changing with each passing day. In the field of calculus, laser will soon surpass ESWL in vitro ultrasonic lithotripsy as the main treatment method. Laser lithotripsy is minimally invasive, eliminates potential side effects, fast lithotripsy, and low recurrence rate make laser lithotripsy gradually win the competition. [0003] Near-infrared high-power lasers with a wavelength of 2um, such as 100W Ho:YAG holmium laser and 120W Tm:YAG laser, are widely used in lithotripsy. However, the frequency of the holmium laser is low, the energy is high, the blasting force of the stone is strong, and the impact and displacement of the stone are serious. The time for the doctor to find the stone during the operation gr...
