Preliminary

Picosecond pulsed seeder laser box

C00175-01 September 2015

1. DESCRIPTION
QC8x1x6x series is a picosecond pulsed seed laser b integrated with 14-pin butterfly DFB laser module of QLD1x6xand QLA1x6x series. 50-psec optical pulse with stable single longitudinal mode can be obtained. 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 be controlled by PC software via
USB interface.
