Cobolt, the Swedish manufacturer of high performance lasers recently released four higher power lasers on the single frequency DPSS laser platform, 05-01.
It is essential in applications that use laser induced fluorescence that no diode light leaks during high speed modulation. In the new MLD series of CW diode lasers, now available from Warsash Scientific , these diodes and their accompanying electronics have been especially designed to be truly off when there is 0 current through the diode.
This ensures that the measured extinction rations during both analogue and digital modulation of these diode lasers is currently the highest available on the market.
Warsash Scientific notes that, during digital modulation, extinction rations of >10,000,000:1 (70dB) have been measured on multiple wavelength units at 10MHz, and for analogue modulation >1,000,000:1 (60dB) at 1mHz.
The four new models in the MLD series of CW diode lasers are as follows:
ZOUK 355NM 20MW
Ideally suited for fluorescence analysis with Hoecht Blue Indo-1 or DAPI, for example, for DNA content analysis or calcium imaging in flow cytometry and confocal TIRF microscopy, as well as Raman spectroscopy on semiconductors.
COBOLT SAMBA 532NM 1,5W
Great for Raman spectroscopy, Interferometry, Ti:Sapphire pumping and Nonlinear optics.
COBOLT FLAMENCO 660NM 500MW
Excellent for Raman spectroscopy, super-resolution STED nanoscopy, Interferometry, DNA sequencing and Particle analysis, eg, DLS/PCS.
COBOLT RUMBA 1064NM 3W
Ideal for Light scatter analysis and optical tweezers.
