QCW 250W 915nm Fiber Coupled Laser Diode
QCW working mode (Quasi-Continuous Wave) is a laser working mode between continuous wave (CW) and pulse working mode. QCW laser works in the form of pulses, but the duration of each pulse is limited, and there is a certain interval between pulses. This working mode enables QCW lasers to reduce heat dissipation and thermal impact while maintaining a certain output power, and is suitable for application scenarios that require high-energy short pulses.
