The QC series is a compact low-power RF driver for AOMs and acousto-optic Q-switches, covering24–110 MHz with up to24 W into50 Ω. Digital modulation, analog power control, zero-crossing synchronization, and configurable output power meet industrial, research, and OEM needs. Contact conduction cooling, compact construction, configurable modes, and integrated modulation provide reliability, heat dissipation, and easy integration in space-limited lasers and optoelectronics. Two TTL digital inputs support fixed-width pulses set internally or variable-width pulses controlled externally. Analog input continuously adjusts RF power. Factory-configurable modes include analog power control, switched analog control, first-pulse suppression, and prepulse elimination to improve laser output and control. Zero-crossing synchronization aligns RF pulses with RF zero crossings to reduce pulse jitter and improve repeatability and stability in timing-sensitive lasers. QC drives Q-switches for stable pulsed-laser generation and AOMs for pulse picking, high-speed intensity modulation, and precision control in industrial and ultrafast lasers, precision processing, research, and optoelectronics.
