What Makes PICOSECOND Unique from Others?


Pico is a unit prefix in the metric system denoting a factor of 10-12 (0.000000000001), or one trillionth. 1 picosecond equals to one trillionth second. Comparing to other laser systems whose time duration is in the scale of nanosecond, Smedtrum ST-221 Picosecondem is in picosecond scale and has more photomechanical effect with less thermal effect on the skin, bringing faster treatments along with better results with almost no side effects in tattoo removal and pigmentation treatments.

Ultra-Short & High Peak Power
Smedtrum ST-221 Picosecond Nd:YAG Laser System offers unique technology featuring the shortest pulse duration in the market of 300-500ps, which enables high peak power up to 500mJ.

Minimal Downtime with Low Risk
The ultra-short pulse of Smedtrum ST-221 Picosecond Nd:YAG Laser System shatters the melanin into tiny, dust-like particles that can be easily eliminated by the body. Thus, brings out great therapeutic results with reduced risk of thermal complications, and restricts the damage area in the targeted zone instead of the surrounding tissues.

Special Features
Smedtrum ST-221 uses Nd: YAG as the laser medium, providing wavelength of 1064 nm, and 532 nm with frequency-doubled KTP lens added. An additional array lens is also available for selection if the skin rejuvenation function is required. The system is equipped with a 7-joints-articulated arm, which enables flexible operations.
