QCED106G series
15/20-ps pulsed seed laser with driver board

C00215-03 November 2022

1. DESCRIPTIONQCED106G series is a 15/20-ps pulsed seed laser integrated with a compact driver board. Butterfly laser modules are
QLD106G series, which employ semiconductor DFB laser diodes emitting at 1064 nm or 1030 nm and can generate
ultra-short pulses of 15 ps for 1064 nm and 20 ps for 1030 nm under gain-switching operation with stable single
longitudinal mode. All operating parameters such as bias currents, pulse voltages and laser diode temperatures can beeasily controlled by GUI on PC through USB interface.

2.

FEATURES• Ultra-short pulse width of 15/20 ps under gain-switching operation with a peak power of 50 mW• Stable single mode operation at 1064 nm or 1030 nm• Wide repetition rate tuning range (12 kHz to 200 MHz for internal clock)• Easy parameter control by GUI on PC

3.

APPLICATIONS• Pulsed seeder for fiber lasers• Time resolved measurement

*3) The power supply is only prepared for operation of the driver board.
*4) When the “Stop” button is checked on GUI for the clock source selection and the pulse generation is turned off, Ib
tuning range turns to be 0-100 mA. Although the board can generate Ib of up to 100 mA, please note that the absolute
maximum rating of the Ib for QLD106G series is 90 mA. This bias current is used to adjust optical pulse shape undergain switch operation.
