QD Laser, Inc. has released the QC2D1x6x series - a picosecond pulsed driver board designed for use with their QLD1x6x-series of 14-pin butterfly DFB lasers spanning the 1030nm to 1240nm range.
This driver board is designed to generate gain-switched optical pulses from 50 to 1000ps with stable single longitudinal mode. The driver board can also directly modulate the laser diodes with 1 to 9ns pulse lengths.
Recently, many fibre lasers for micromachining have come to adopt MOPA (Master Oscillator Power Amplifier) system using semiconductor seed lasers in order to produce highly controlled pulse characteristics and repetition rate. In particular, high-quality glazing and marking etc., requires psec pulses to reduce heat effects on processed materials.
QDL's QLD1x6x series of DFB laser diode modules can produce 50ps optical pulses with stable single-mode oscillation and are widely adopted in these applications.
The QC2D1x6x pulsed driver board is being adopted by many customers as a quick and reliable solution to achieve stable, flexible, and easy operation of the laser diodes.
The new product of QC2D1x6x series, featuring stable 50 psec optical pulse generation, will help customers design and develop psec fiber lasers, and is suitable for micromachining, sensing and time resolved measurement.
The main features of this product are:-
・ Integration of QLD1x6x series of 1020 to 1180 nm DFB laser modules with stable single-mode oscillation
・ 50psec optical pulse generation, tunable pulse width up to 9 nsec, and CW operation
・ Peak optical output power of 100 mW, typical under 50 psec operation
・ Tunable repetition rate of single shot to 250MHz
・ Fine wavelength tuning by temperature control of LD chips
・ Flexible parameter control via USB interface
・ Single +5V power supply
