The Laser Quantum axiom 660 laser has a new architecture that delivers high CW power whilst incorporating all of the active optics within the laser lead. The axiom lends itself to easy integration into equipment due to its ultra-compact power supply unit, without the complexities associated with fibre delivery.

The axiom 660 is ideally suited to a range of applications including Particle Imaging Velocimetry (PIV), Raman imaging, and a wide range of fluorescence imaging techniques. The high-power enables a brighter image in PIV and imaging of Raman emission over a larger area. With its high power, excellent beam characteristics and size, the axiom 660 addresses several fluorescent dyes including Atto 647N and Atto 655 for fluorescence imaging and super resolution microscopy.
