A stable and effective CuBr laser is demonstrated for the treatment of vascular lesions. The twolasing wavelengths of 511 nm and 578 nm can be adjusted to any mixing ratio by using a 6-hole filter. The output power is stabilized to maintain the same peak power by using a proportional integraldifferential (PID) modulator. For various treatments and treatment effects, the laser outputs, suchas the output power, spot size, and beam mode can be controlled. Preclinical test using Koreanrabbits showed that the fabricated CuBr laser had a positive effect when treating vascular lesions. The blood vessels of the rabbit’s ear were well ablated after irradiation at a laser output power of8 W in a 1 mm spot in the top-hat mode.
