QC8x1x6x series
Picosecond pulsed seeder laser box

C00175-04 March 2024

1. DESCRIPTION
QC8x1x6x series is a picosecond pulsed seed laser box integrated with 14-pin butterfly DFB laser module of
QLD1x6x and QLA1x6x series. 50 ps optical pulse with stable single longitudinal mode can be obtained. Flexible andeasy 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 be controlled by PC softwarevia USB interface.

2.

FEATURES• 1018-1188 nm DFB-LD/DFB-SOA LD integrated• 50 ps gain-switched pulse generation• >30 mW peak power• Internal / External clock operation• Single shot to 250 MHz repetition rate
• Flexible parameter control via USB• Plug and Play

3.

APPLICATIONS• Pulsed seeder for fiber lasers• Time resolved measurement
