Technical content

Prometheus is a frequency doubled Nd:YAG laser providing both 532 nm and 1064 nm outputs in a single package. Being based on a Non-Planar Ring Oscillator (NPRO) configuration Prometheus features frequency and intensity stability parame- ters unmatched by any other commercial product. Prometheus laser is simple to stabilize in temperature and easy to fine-tune by using an integrated PZT. Prometheus is available at power levels of 20 mW and 100 mW at 532 nm and corresponding powers of 500 mW and 1500 mW at 1064 nm from the second output. Prometheus is an ideal laser source for applications such as Iodine frequency stabilization systems (please enquire about iodine based options), optical length and frequency standards, quantum optics studies, micro-cavity experiments, nonlinear optics pumping, gravitational waves studies, optical hetero- dyning and others. Features & Benefits

  • Monolithic non-planar ring oscillator (NPRO) technology for ultra-stable and narrow linewidth
  • Fundamental and doubled wave- lengths available simultaneously
  • Efficient and stable extra-cavity doubling stage
  • Extremely long coherence length
  • Noise Eater – active intensity noise reduction technology
  • User-installed, turn-key operation
  • Low noise control electronics

Applications

  • Iodine Frequency Stabilization
  • Gravitational Wave Studies
  • Laser-based Metrology
  • Quantum Optics (optical trapping, optical lattice, squeezing)
  • Nonlinear Optics Pump Source (SHG, DFG, OPO) Ultra-Narrow Linewidth CW DPSS Green Laser
