Superpulsed vs. Continuous Wave

Can I adjust my CW laser to emit superpulsed laser?

The quick answer is no.  It’s similar to changing a gasoline engine to a diesel engine. They are two very different ways of generating power.

Generally speaking, superpulsed (SP) lasers generate high peak power with relatively lower average power for deep tissue penetration. Specific laser diodes are required to produce high peak powers and high pulse rates and use very short pulse durations such as 10 or 200 nanoseconds to deliver safe average power. Superpulsed diodes producing pulse rates of 30,000 pulses per second (30 kHz) or higher are biostimulative for gene expression (activating genes), amplifying tissue healing. So, superpulsed lasers are designed primarily for pain relief and tissue healing. They wouldn’t be appropriate or useful to perform soft tissue surgery.

Continuous wave (CW) lasers are able to produce high average powers, but relatively low peak powers. Specifically, the maximum average power is also the maximum peak power. A 60W CW laser has equal maximum peak and average powers of 60W. Diodes used in CW lasers have relatively long pulse duration, creating high thermal effects that would quickly degrade the diode. With high peak powers they typically have low pulse rates to reduce the thermal accumulation that would be destructive to both the diode and the target tissue. However, this thermal effect is used productively for soft tissue surgery (ablating or carbonizing the tissue).

SP and CW laser diodes are the “engines” that produce their respective laser beams with different properties, different benefits.
