HQF series high Energy Sub-nanosecond lasers are flash lamp pumped, passively Q-switched, independently developed by Reallight, can produce particularly high pulse energy at short pulse duration(pulse width). This series of products includes two wavelengths of 1064nm and 532nm. The pulse duration(pulse width) can go down to 300ps(0.3ns), therefore it is also called as a kind of picosecond laser . Various models operate with repetition rates up to 10Hz. Single or dual-rod oscillators with two amplifier stages resulting in output energies up to 500mJ per pulse. Such series lasers are especially suitable for medical cosmetic(Medical aesthetic) applications, such as chloasma removal, tattoo removal, pigmentation treatment and other pigment removal treatment.
