This device is a solid-state thulium laser with pulsed/continuous modes. At a wavelength of 1940 nm, it has an extremely high water absorption coefficient, enabling precise tissue ablation with minimal thermal injury. Designed with switchable continuous and pulsed modes, it delivers a maximum pulse power of 1000 W and a maximum average power of 120 W, suitable for both soft tissue cutting and the treatment of urinary calculi.
