Abstract

A laser is a light source that uses for any
kinds of medical application. Diode Laser is one laser type
using in the medical application such as Photodynamic
Therapy and Photodynamic inactivation. Photodynamic
Therapy is one of non-invasive therapy using for many
therapies such as antimicrobial therapy, rejuvenating skin
therapy, anti-aging skin therapy, etc. This therapy is using
a light source with specific characteristics of wavelength in
some case are using Light-sensitive molecules. This
research aims to determine the potential of the diode laser
for photodynamic therapy instrument. Diode Laser with
wavelength value 660nm is Red Laser Diode that has main
power output 79,4 mW. The application was using 1 cm
clearance with the 30s of time exposure. The result showed
that for Diode Laser (λ) 660nm using 7,8x10-2 W input
power produce 77,78 mW output power; has operational
temperature 53.56oC and light beam 4.2 mm2
