What is a holmium laser?

Holmium laser is a new type of laser generated by pulsed solid-state laser device. It uses yttrium aluminum garnet (YAG) as the activation medium, and is doped with sensitizing ion Cr, energy-transmitting ion thulium (Tm) and activating ion Ho (Cr:Tm:Ho:YAG). Can be used in urology, otolaryngology, dermatology, gynecology and other departments. Laser surgery is non-invasive or minimally invasive, and the treatment of patients is very painful.

The application of Ho: YAG laser makes the treatment of urinary calculi go to a new level. Holmium laser is a kind of pulsed laser with the wavelength of 2. 1μm, and it is the latest laser used in many surgical operations at present.

The generated energy can evaporate the water between the end of the optical fiber and the stone, form tiny bubbles, transfer energy to the stone, and make the stone be ground into powder. Water absorbs a lot of energy and reduces the damage to surrounding tissues. At the same time, the penetration depth of Holmium laser into human tissues is very shallow, only 0.38 mm, so the damage to surrounding tissues can be minimized when crushing stones, and the safety is extremely high.
