Laser manufacturer Cobolt AB said it shipped its 10,000th laser in February. That unit, a Samba 532-nm, 300-mW single frequency laser, was delivered to Sam Johnson from the Photonic Nanomaterials Group at the University of Oxford.

Johnson is studying nitrogen vacancy (N-V) defects in diamond lattices, which could hold the key to the future of quantum computing. The Cobolt Samba 532-nm is used in a scanning confocal microscope setup to excite the diamond, the red emission highlighting the N-V lattice defect. Johnson said Cobolt was the first choice due to the higher available output power, excellent power stability and TEM00 beam, as well as quick delivery time. Founded in 2000 with roots in the Royal Institute of Technology in Stockholm, Cobolt, a Hubner Group Company, supplies CW and Q-switched lasers for standalone use in labs or OEM integration in equipment for fluorescence analysis, Raman spectroscopy, interferometric metrology, micromachining and environmental monitoring.
