The manual describes the treatment as selective photothermolysis: a Q-switched pulse is absorbed in a very short time (around 10 nanoseconds) by pigment particles in the lesion. The particles heat rapidly, swell and fragment, and are then cleared by macrophages and ordinary skin turnover. The manual notes that the heat is taken up mainly by the pigment, not by the surrounding skin.
This is a nanosecond Q-switched machine, not a picosecond platform. The pulse width given in the manual is less than 10 nanoseconds. Pulse rate, spot size and energy level are set on the screen; a red aiming beam marks the target.
Cooling combines a water circuit, air cooling and temperature-control cooling. Operation follows a short sequence: pre-ignite the flashlamp, wait for the ready state, then fire from the handpiece. The screen keeps both a session shot count and a lifetime shot count.
Questions
Is this a picosecond machine?
No. SQ-1 is a Q-switched nanosecond Nd:YAG. The manual gives a pulse width of less than 10 nanoseconds. Picosecond platforms are a separate range and are not listed on this site.
Which wavelengths are fitted?
1064 nm, 532 nm and 1320 nm. The gold treatment head is 1064 nm, the blue head is 532 nm, and the black head is 1320 nm.
What is in the box?
The packing list in the manual is: one machine, one handpiece with three treatment heads, one power cord, one pair of goggles and one funnel.
