QD Laser supply a range of single longitudinal mode high power Quantum Well DFB laser diodes from 1020nm to 1188nm.
These lasers offer excellent single mode stability and are suitable for CW operation, nanosecond modulation and short pulse (down to 215ps) gain-switched operation. They are ideally suited as the seed source of a fibre laser system; for gas sensing and as a source for Second Harmonic Generation (SHG) when combined with PPLN (Periodically-Poled LiNbO3).
The laser diodes are available in a standard 14-pin butterfly package with an optical isolator, monitor photodiode, thermoelectric cooler (TEC) and thermistor. The package is pigtailed with polarisation-maintaining optical fibre (PMF).
Recent additions to the range are the QLD106P-xxD0 Series of lasers at 1030nm, 1053nm, 1064nm, 1083nm, 1120nm and 1180nm which are intended for pulsed operation in the 1 to 10 nanosecond range and achieve >400mW peak power under these conditions.
The QLD106G-3010 (1030nm) and QLD106G-6410 (1064nm) lasers feature a high speed 7-pin butterfly package with an SMPM RF coaxial connector. These devices are optimised for high speed direct modulation and are also capable of gain-switched pulses as short as 15ps.
QD Laser also offer 100mW CW devices at 1064nm, 1122nm and 1188nm based on their monolithic Distributed Feedback / Semiconductor Optical Amplifier (DFB/SOA) chip technology (QLA1061-64A0, QLA1161-22A0 & QLA1161-88A0) as well as a 1060nm gain chip (QLF101A) which is available as a chip or Chip-on-substrate (COS).
