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.
