QC9D1x6x Series
Nanosecond high power pulsed seeder laser board

C00217-04 March 2024

1. DESCRIPTION
QC9D1x6x series is a nanosecond high power pulsed seed laser board integrated with 14-pin butterfly DFB laser
module of QLD1x61, QLD1x6P and QLD106D series. Electrical pulse width can be tuned from 5ns to 125ns, andmaximum current as driver ability is 2A. Flexible and easy operation can be achieved with both external and internal
trigger. All operation parameters including pulse peak current and laser diode temperature can be controlled by PC
software via USB interface. Only single +5V power supply is required for the board operation.
2.

FEATURES• QLD1x61 or QLD1x6P series with wavelength of 1018-1122 nm and 1040-1188 nm integrated (1064 nm onlyfor QLD106D series)• 5 to 125 ns electrical pulse generation• High output power under pulsed operation• Internal / External clock operation• 1.5 kHz to 2 MHz repetition rate with internal clock operations• Flexible parameter control via USB• Plug and Play
