Abstract :
The demand for fair skin has influenced the
beauty clinics’ advancement in treatment and tools. Laser
is one of the innovations which will minimize the pain
during the treatment and obtain a prompt result.
However, to meet the therapeutic needs, a system for
controlling the power and energy of laser exposure is
needed for each wavelength. This study is conducted to
design and build an instrumentation system for controlling
the Red and Blue-Violet laser power and time as a beauty
therapy application. This study designed a red and blue
laser control system to emit six energy variations and set
the output power output to 3 levels. Thus, the current
source for the red laser and the voltage source values for
the blue laser need to be adjusted to set the current and
voltage source variants using the LM317 circuit. The test
results of the timeliness value of the system obtained that
the percentage of timeliness is 99.88%. It can be assumed
that the laser exposure time is relatively accurate. Thus,
the value of the energy accuracy depends on the value of
the power and time stability. In testing the energy stability
of the design of the red diode laser control system, it is
99.5%, and for the blue-violet diode laser, it is 98.5%. In
conclusion, the diode laser output power is relatively
stable, and the system can work with a stable and precise
dose of energy, output power, and time.
