Superpulse is a specific waveform commonly used in CO2 laser systems either in a pulsed or continuous pattern. Superpulsed lasers are capable of emitting several thousand bursts of power per second. The superpulse of a laser system is created with extremely short radiant output and corresponding longer rest period per pulse. The peak power is greater than the energy delivered by continuous wave however, the total fluence delivered by a superpulse is usually lower than that of continuous or pulsed wave.
Superpulse waveform can also be pulsed such that several micropulses of laser energy output are created during each macropulse of the superpulse waveform. In general, macropulses of 25 ms are created in a single superpulse waveform in pulsed mode. The radiant output of a single superpulse waveform ranges between 200 and 300 µs. These measures enable the use of superpulse lasers in applications which involve penetration of target tissues of human.
Superpulsed laser can penetrate deep into the tissue up to 10 to 13 cm as ultimately short pulses are quickly absorbed at the cellular level. It produces a high peak impulse of intense light for a fraction of a second and therefore has no chance of causing thermal damage to tissue. The power density of these very high pulses produces an extremely high saturation and photon flux, which ensure a stronger therapeutic effect.
