QCBA1x61-xxA0 Series
Picosecond pulsed driver board for DFB/SOA gain switched operation

C00222-02 March 2024

1. DESCRIPTIONQCBA1x61-xxA0 series is a picosecond pulsed seed laser board integrated with 14-pin butterfly DFB-SOA laser
module of QLA1x61-xxA0. 50 ps optical pulse with stable single longitudinal mode is obtained under gain-switched
operation for DFB section, and SOA section is simultaneously operated with DFB section to amplify gain-switchedpulse. Flexible and easy operation can be achieved with both external and internal trigger from single shot to 250MHz
high repetition rate. All operation parameters including pulse peak current and laser diode temperature can becontrolled by PC software via USB interface. Only single +5V power supply is required for the board operation.
