Product of the month: opus 660
The opus 660 laser has proved ideal for imaging living cells and tissue using the STimulated Emission Depletion (STED) microscopy technique, with the only commercially available 1.5 W high power 660 nm beam, the opus 660 is able to create the STED de-excitation needed to create a sharp undepleted fluorescent image. By controlling the red STED laser output, resolution can be greatly increased over standard imaging techniques and details below 40 nm can now be imaged.
The size of the unquenched spot decreases with increasing power from the STED de-excitation laser and Laser Quantum’s opus 660 laser is ideal for this application, not only due to the 1.5 W available power, but also, as it has an M2 value of close to unity, allowing the creation of the low-order Laguerre-Gaussian beam.
