QCW laser SM

GZTECH 150W air-cooled QCW products, single-mode and multi-mode optional, suitable for precision welding and cutting applications of metals/ceramics and other materials

GZTECH QCW lasers support simultaneous operation in both continuous and high peak power pulsed modes and can handle processing tasks that previously required two different lasers, unlike conventional continuous continuous (CW) lasers, whose peak and average powers are always the same, while the peak power of the QCW laser in pulsed mode is 10 times higher than the average power. GZTECH QCW lasers can generate microsecond and millisecond pulses with high energies at repetition rates from tens of hertz to several kilohertz and achieve average and peak powers of several kilowatts.


a.GZTECH 150W air-cooled QCW products, peak 1500W, single-mode and multi-mode optional, suitable for cutting, scribing, drilling and other applications of ceramic and metal materials, and can also be used for precision welding of metal materials, especially in the 3C industry .

b. GZTECH QCW lasers have low average power, high peak value, high single pulse energy
