BSR Chromalase™ II Diode Laser Modules

Fully Integrated Diode Lasers Provide a Very High Beam Quality

The Chromalase II™ family of laser modules is Blue Sky’s second generation of high performance laser modules. They have been optimized to meet the demanding performance requirements of medical, life sciences and automated instrumentation. The Chromalase II™ product family incorporates highly integrated sophisticated electronics for laser drive and protection, modulation and feedback functions.  This ultra compact stand alone assembly is RoHs compliant and can be ordered with a variety of collimation optics which allows easy integration into your system.  A wide variety of wavelength and power options are available including the very popular 405nm, 488nm, 532nm and 635nm products

Key Features

  • Diffraction limited Optical Performance
  • Power stability < 0.5% in 2 hours
  • Circular or Elliptical Output Beams
  • Variable Output Power
  • Integrated drive and power electronics
  • < 0.5% Optical Noise (RMS)
  • < 12W electrical Power consumption
  • Beam alignment accuracy < 5mRad
  • Solid State Reliability
  • Pointing stability < 10 µrad/ºC

 

BSR's design incorporates standardised control and alarm Firmware, protection circuitry and low noise operation into a compact, stand alone assembly.  Everything you need to operate this laser from a simple 12volt DC supply is integrated in the laser module. The laser is temperature stabilized with a thermoelectric cooler (TEC) and the integrated controller includes; laser driver, output power stabilization, adjustable power level control, modulation capability, reverse and over voltage protection, and ESD-fast transient suppression circuitry.

Each semiconductor laser diode system can be  ordered with or without Blue Sky’s patented µLens or micro-optic beam correction optics. Systems with µLens will have near perfect Gaussian and circular beam shapes and corrected laser diode wave front distortions.

Laser systems without the micro-optic beam correction have all the advantages of our small, highly integrated packaging while retaining the standard elliptical shape (typical 3:1 aspect ratio) of semiconductor lasers.
