MOPA vs Q-Switched Laser: Which Is Better? - HeatSign

WebJan 15, 2024 · Q-switched lasers are widely used in laser liposuction, as they can effectively reduce unwanted fat while minimizing tissue damage. One 2014 study found that Q-switched laser liposuction resulted in 54% less blood loss compared to traditional liposuction. 8. Acne scars can be effectively treated with a Q-switched laser. WebQ-switched lasers cannot regulate the pulse width parameters due to its own architecture, so it is difficult to fine-tune the line drawn. The MOPA laser can adjust the pulse width and frequency parameters flexibly, which can not only make the line drawn fine, but also the edges appear smooth and not rough.
