These air-cooled drivers deliver precise, high-current control for diode lasers, bars, and arrays in pulsed (QCW) and continuous wave (CW) modes—ideal for research, industrial, medical, defense, and pumping applications.

PCX-7421 (Pulsed/QCW Focus):

• Adjustable pulsed output current: 50 mA – 21.5 A
• Pulse width: 50 ns – 500 ms
• Rise/fall time: <25 ns
• Compliance voltage: 24 V
• Internal pulse rep rate: 40 Hz – 100 kHz
• External trigger rep rate: single-shot to 1 MHz
• High-power, air-cooled design for reliable operation

PCX-7121 (CW + QCW Capabilities):

• CW (DC) output: 0.05 A – 5.8 A
• QCW/pulsed output: 50 mA – 21.5 A
• Bias + pulse mode: CW bias 0.05 A – 5.8 A, pulse up to 15.7 A above bias
• Independent triggering of bias current and main pulse (advanced feature)
• Versatile for combined continuous and pulsed drive scenarios

Both models provide exceptional performance, fast edges, and flexibility for driving high-power laser diodes with accuracy and repeatability.
