The PureBeam laser from StockerYale Canada (Montreal) is a temperature-stabilized, fiber-coupled device for a wide range of biomedical applications, including spectroscopy, fluorescence, confocal microscopy, biodetection, and DNA sequencing. This high-output power laser has integrated drive electronics and laser-welded mechanical components. The PureBeam laser features a single-mode optical fiber (phase modulation optional) delivery system, and provides exceptional power stability and low noise at the fiber exit.
