Cobalt 05-01 Series DPSS lasers

Cobolt has released four higher power lasers on the single-frequency DPSS laser platform 05-01. No diode light leakage during high-speed modulation for applications using laser-induced fluorescence is essential.

In the MLD series of CW diode lasers, these diodes and their accompanying electronics have been designed to be truly off when there is zero current through the diode. As a result, the measured extinction rations during both analog and digital modulation are said to be the highest available on the market. During digital modulation, extinction rations of >10,000,000:1 (70 dB) have been measured on multiple wavelength units at 10 MHz and for analog modulation >1,000,000:1 (60 dB) at 1 mHz.

The Zouk 355 nm 20 mW is suitable for fluorescence analysis with Hoecht Blue Indo-1 or DAPI, eg, for DNA content analysis or calcium imaging in flow cytometry and confocal TIRF microscopy, as well as Raman spectroscopy on semiconductors.

The Samba 532 nm 1.5 W is good for Raman spectroscopy, interferometry, Ti:sapphire pumping and nonlinear optics.

The Flamenco 660 nm 500 mW is good for Raman spectroscopy, super-resolution STED nanoscopy, interferometry, DNA sequencing and particle analysis, eg, DLS/PCS.

The Rumba 1064 nm 3 W is suitable for light scatter analysis and optical tweezers.
