High‐power laser vaporization of the canine prostate using a 110 W Thulium fiber laser at 1.91 μm

The Thulium fiber laser may have several advantages over current urology lasers, including smaller size, more efficient operation, improved spatial beam quality, more precise tissue incision, and operation in pulsed or continuous‐wave modes. Previous laser‐tissue interaction studies utilizing the Thulium fiber laser have been limited to laser powers of less than 5 W, restricting potential medical applications. This study describes the preliminary testing of a high‐power Thulium fiber laser for vaporization of the canine prostate, ex vivo.
