Single frequency, CW diode pumped lasers

The Cobolt 04-01 Series lasers are continuous-wave diode-pumped lasers (DPL) operating at a fixed wavelength between 457 nm and 1064 nm. Single frequency operation provides an ultra
narrow spectral linewidth, long coherence length and excellent spectral purity. The lasers are designed and manufactured to ensure a high level of reliability.

  • 457 nm – 1064 nm, CW up to 400 mW
  • Linewidth < 1 MHz, (>100 m coherence length)
  • TEM00 beam
  • Low noise, <0.25% rms
  • Wavelength stability <1 pm (over ± 2 °C and 8 hrs)
  • Optional integrated modulation up to 3MHz
  • Fiber pigtailed option
  • Ultra-robust, hermetically sealed packages, proven reliability
  • Up to 24 months warranty, unlimited hours


Perfect for interferometry, Raman, holography, microscopy.
