Laser specialist Omicron's newest diode laser, Deepstar, does not indicate any further residual fluorescence content in the 'off' moment during modulation, even with very high modulation rates
The newest diode laser from the Omicron house with the appropriate name "Deepstar" does not indicate any further residual fluorescence content in the 'off' moment during modulation, even with very high modulation rates, and thus achieves almost infinite modulation capability.
With the innovative temperature-stabilized diode laser of the LDM Series with high-speed modulation greater than 100megahertz, the Omicron development team has created a sensational breakthrough in modulation technology for diode lasers.
The analogue and digitally-modulated laser diode module Deepstar offers a modulation depth of significantly more than 100,000:1.
These lasers are particularly suitable for fluorescence excitation and all applications where absolutely no remaining light is allowed in the 'off' moment during the modulation.
Deepstar is said to be the ideal source of light, for example for confocal laser scanning microscopy and flow cytometry.
With the ultradeep analogue modulation greater than 10MHz and a digital modulation greater than 100MHz with a signal rise and signal fall time of less than two nanoseconds, Deepstar is also suitable for those high-performance applications which, up to now, were possible only with CW lasers and AO modulators.
The Deepstar diode laser is available with 20milliwatt (mW) at 375nanometers (nm), 60mW at 405nm, 50mW at 442nm, 20mW at 473nm, as well as with different powers up to 150mW at 635 to 980nm.
The laser has a controller which is equipped with an RS-232 interface and is operated with 24 volt DC voltage.
The analogue and the digital signal input can be configured with respect to voltage and impedance so that adaptation to the existing signal sources can be implemented easily.
Furthermore, the modular principle of the laser heads of the LDM series offers further possibilities for customer-specific adaptation, such as single-mode fiber coupling with an efficiency of up to 75 percent, collimation for 0.5 to 15millimeters of beam diameter, focussing objectives down to under one micrometer and a lot more.
