Chromalase™ II Diode Laser Modules

Chromalase II Laser Diode Modules

Fully integrated diode lasers provide a very high beam quality

The ChromaLase™ II range of diode laser modules from Blue Sky Research incorporate a UV, visible or infrared semiconductor laser diode that can be specified with a proprietary micro lens (μLens). The μLens shapes and corrects the inherent defects in the light emitted from a standard semiconductor laser. The integrated beam correction results in a near-Gaussian and circular beam shape and also helps correct the wavefront distortions inherent in laser diodes. This makes ChromaLase a perfect choice for high performance applications, and avoids the extra cost and complexity of external beam conditioning optics that are employed with normal diode lasers.

ChromaLase™ II diode laser modules are available with a wide variety of wavelength & power options, including 375, 405, 440, 473, 488, 532, 635, 658 & 785 nm outputs. Each module is a complete, ultra-compact, stand-alone laser – everything that you need to operate the laser from a simple 12 Volt DC supply is integrated within the laser module. The laser is temperature stabilised with a thermoelectric cooler (TEC) and the integrated controller includes laser driver, output power stabilisation, power level control, reverse and over voltage protection, fast transient and ESD suppression.

When equipped with a μLens, a Chromalase II module provides a Gaussian, circular, diffraction-limited beam in the far-field with an ellipticity of < 1.15. With a power stability of < 0.5% (over 1 hour), a noise level of < 0.5% (20Hz - 2MHz) and the ability to be modulated at up to 10kHz as standard (100kHz is optional)*, Chromalase II diode laser modules trully possess the performance necessary for use in demanding applications such as flow cytometry, confocal microscopy, life sciences and biotechnology, food safety and optical metrology.

The latest addition to the Chromalase II family is a higher power 50mW version of the 488nm diode laser module. The new ChromaLase II 488 produces over twice the power of its predecessor.

(* 532nm Chromalase cannot be modulated).
