Our laser machine has both single-pulse and dual-pulse. The single-pulse's intensity is more suitable for tattoo removal and the dual-pulse is more gentle and suitable for removing freckles. 1064 and 532 are two different wavelengths. 1064 is more suitable for removing deep color pigment, and 532 for removing light color pigment. Our machine is equipped with a red light, which makes the treatment area easier to find. The energy range is different depending on the pulse and wavelength chosen. If a single pulse-532nm is chosen, the energy range is 40-400J. And if a dual pulse-532nm is chosen, the energy range is 80-800J. If a single pulse-1064nm is chosen, the energy range is 40-800J. And if a dual pulse-1064nm is chosen, the energy range is 80-1600J. This is the energy density. The energy density will vary with the energy and spot size. It is easier for doctors to do treatment more professionally. The frequency can be adjusted in the range of 1 to 10HZ. 1064 is suitable for removing deep color pigment and 532 for removing light color pigment. The machine is enclosed in an ABS shell. It is made of metal frame structure, which is suitable for long-term transportation. Inside the machine, the modular design is adopted, which is convenient for maintenance. It is made up of three systems: the control system, the power supply system and the cooling system. It has two special advantages: the use of OPT power supply ensures the stable output of energy. It has water temperature and water flow protection system. The laser lifetime is 30 million times, which can be used permanently.
