QD Laser have released the QLM4F02-series compact multi-wavelength laser module platform which can be populated with up to 4 wavelengths of singlemode laser diodes with a single fibre-coupled output.


4 Wavelength 488nm4 Wavelength 660nm4 Wavelength 561nm


A choice of one of QDL's QDL0593-series compact Visible Laser Modules (cVLMs) at 532nm, 561nm and 594nm is available. These lasers combine narrow linewidth near infrared DFB/SOA lasers with waveguide Periodically Poled Lithium Niobate (PPLN) frequency doubling to provide narrow linewidth and excellent stability.


Up to three further wavelengths of Fabry-Perot laser diodes can be specified in the range 405nm to 905nm.


The module package is a compact 80mm x 80mm x 30mm and incorporates a thermoelectroic cooler for active temperature control and stabilisation. There is a choice of singlemode or polarisation maintaining fibre pigtail with FC/PC or FC/APC connector.


A typical application for the 4-wavelength multiplexed module is flow cytometry. A frequently used combination of wavelengths for flow cytometry is 405nm, 488nm, 561nm and 640nm and these are offered in the standard QLM4F02-40485664-1S which features a singlemode pigtail.


Other applications include Ophthalmology/SLO devices combining RGB and NIR lasers - for example the QLM4F02-48536678-1P (488nm, 532nm, 660nm and 785nm) with PM fibre output.

QBB4M01 4 ColourDriver





QD Laser have also developed a control board for the 4-colour module. The QBB4M01 driver optimises the DFB and SOA current of the 532/561/594nm laser along with the FP operating currents and TEC. Control of the lasers' power, CW or direct modulation and temperature is via USB and the driver board requires a single 12V supply.
