Coherent Astrella femtosecond laser

Photo of Coherent Astrella Femtosecond Laser The Astrella laser is a femtosecond laser system from Coherent that produces 35 fs pulses and is designed to be very stable (0.5% rms power stability), with a high beam quality (M2 < 1.25). There are three available beam lines with specifications included in the table above. To complement the Astrella laser, a large range of sample translation stages, beam manipulation optics, and spectroscopy equipment are available upon request.

Applications of the Astrella laser include:
  • micro/nanoscale surface texturing
  • surface functionalization
  • machining
  • precision cutting and drilling
  • spectroscopy
Experimental setups can be customized to specific user applications. The laser is operated by trained laser specialists who assist all end users of the laser.
