Mr. Yoshitaka Yokoyama, Project Leader at QD Laser attended Photonex 2012 at the Ricoh Arena in Coventry and gave a presentation entitled "Compact visible laser modules and NIR DFBs with high speed modulation"
The abstract of the presentation reads:-
QD Laser, an offshoot of Fujitsu Laboratories, are developing a range of visible laser diode modules incorporating monolithic NIR Distributed Feedback laser/Semiconductor Optical Amplifier (DFB/SOA) with passive frequency-doubling using a Periodically-Poled Lithium Niobate (PPLN) waveguide.
The low power consumption lasers are packaged in a compact (4x6x22mm) package and emit up to 50mW at 532nm, 561nm and 594nm with narrow linewidth.
These lasers offer quick start-up with excellent short- and long-term noise performance and can be directly modulated at up to 100MHz with stable single-frequency output.
QDL’s NIR DFB laser diodes incorporate proprietary grating structures. Intended primarily as seed lasers in fibre laser systems the Butterfly-packaged devices incorporate TEC, MPD and isolator with 30mW PM fibre output at 1053nm, 1064nm, 1118nm and 1180nm.
100mW versions are under development as are additional wavelengths in the 1000-1200nm region.
In addition to excellent CW performance these lasers can be modulated using the Gain-Switched technique to achieve pulse width of 50psec.
QDL will present data on these lasers and discuss typical applications for both technologies.
