Picosecond laser and Q switch ND YAG laser difference

At picosecond laser pulse width, the resulting photomechanical stress on the target pigment particles causes their volume to expand instantaneously, causing the target to decompose into particles that are more easily removed by phagocytes.
The q-switched laser has a pulse width of more than 5ns, and its photomechanical stress is less efficient than picosecond laser.
Produces large particles with a long pulse width that scatters energy towards surrounding tissues, leading to a risk of thermal damage.
Therefore, picosecond laser provides a more effective and safer treatment than q-switched laser.
