The Genesis 355-150 S laser from Coherent is said to deliver more than 150mW of TEM00 output for flow cytometry and other live-cell bio applications.
The laser is based on the company's optically pumped semiconductor laser (OPSL) technology, which is used in many biomedical applications for visible wavelengths.
The laser is a true CW source of 355nm UV laser light, avoiding the potential high-peak power problems arising from older quasi CW lasers.
With low output noise and a single spatial output mode (M2 <1.2), the Genesis 355-150 S laser is ideal for high-throughput applications needing best signal-to-noise ratio data.
The high power of the Genesis 355-150 S is intended to increase the throughput of live-cell applications including flow cytometry, such as egg and fertilised-egg sorting, where the peak power of alternative, mode-locked lasers poses significant risk of mutagenic damage to the DNA in the sorted cells.
It is also a good source for other fluorescence-based applications, including confocal microscopy, where its short wavelength and low M2 beam provide optimum excitation of Hoechst and Indo dyes.
Moreover, these confocal microscopes often rely on fibre delivery, which can be problematic for the high-peak power levels of quasi CW lasers.
