An ultra-low noise amplifier and efficient frequency doubling are then employed to generate stable, high power 488, 514 & 532nm wavelength light for applications such as atom cooling, holography, Ti:sapphire laser pumping, spectroscopy and argon ion laser replacement amongst others. ALS ultra-low noise fibre laser technology is particularly useful for the most demanding applications requiring excellent power, pointing or frequency stability. Industrial holography users have validated Azurlight Systems fibre lasers as the only solution to replace and exceed the performance of Argon lasers, especially in the central frequency stability and pointing stability. 

Applications:

  • Atom cooling
  • Holography
  • Ti:sapphire laser pumping
  • Raman spectroscopy
  • High power argon ion laser replacement
  • Interferometry

Key Features:

  • Based on patented technology and major advances in fibre laser and system design, ALS-VIS lasers offer diffraction limited output powers in excess of 10 W.
  • ALS-VIS ultra-low noise fibre laser technology is particularly interesting for the most demanding applications requiring an excellent stability in terms of power, pointing or frequency.
  • A full spectral control of the output is possible with linewidths <200kHz (single longitudinal mode) and drift of the central wavelength <0.1pm over several hours.
  • The passive optical head avoids any heat generation (no fan, no chiller) to offer the best performances and easy integration.
  • Power sharing over several output ports (2, 4, 8, 16...) and fibre re-coupling are available as options, dramatically reducing the cost for parallel processing applications.
