The new Cube 640-100 from Coherent is one of the highest powered 640nm (red) diode laser-modules commercially available.
It is a single emitter based, turnkey system.
It offers 100mW of CW output in a high quality (M<1.5) small-diameter beam (diameter is 1.0mm), making it more than twice as powerful as previous products available at this wavelength.
The Cube 640-100 is intended for flow cytometry applications utilising dyes originally optimised for the 633nm output of helium neon lasers.
In this context, the high output-power of this new laser will deliver higher throughput (scan rate) and improved signal-to-noise.
The Cube 640-100 has a maximum output wavelength of 644nm.
(As is typical for laser diode modules, the 640nm is a nominal wavelength specification.) This hard limit ensures high transmission through the laser emission bandpass filters typically used in cytomtery instrumentation, as well as excellent blocking by commonly used detector filters.
Another key application for the Cube 640-100 is high-throughput screening in drug discovery.
This new laser also leverages the benefits of Coherent's Cube architecture for digital (bandwidth 150MHz) and analogue modulation (bandwidth 350kHz) and easy system integration through the use of USB, RS-232 and analogue interfaces.
It uses the same footprint as lower powered Cube lasers, thus facilitating upgrade for systems builders.
As with other lasers in this series, the Cube 640-100 is backed with a one-year, unlimited-use warranty.
