The surgical diode laser has two operation modes – continuous mode and repeat pulse mode. Optical fibers with diameter of 200, 400, 600, 800, 1000um can be used as its delivery system. The Diode laser has quick vaporization effect and good hemostatic effect. The laser beam has no electric stimulation to nerve and tissue, there will be little injury, little pain and few complications on the patient, and the hospitalization is short. The laser can match all kinds of endoscopies by using optical fiber of different diameters. The laser also has flexible application in open surgery.
The diode laser has a high electro-optic conversion rate, producing little excess heat, so it does not require a large water cooling system like Nd:YAG or CO2 lasers, which makes it small in size and light in weight. Meanwhile, the diode laser does not contain high-voltage high-temperature components, providing longer service life, more stable power output, lower power consumption and more flexible application.
