What sets us apart?

External Diode Laser Cavities (ECDL) and  Master Oscillator Power amplifier (MOPA) are available in Littrow or Littman configuration. Compromise between large mode hope free tuning range and high output power have to be done.

  • Littrow configuration is best for high power and standard mode hope free tuning range.
  • Littman configuration is best for large mode hope free tuning range thanks to patented cavity and standard output power.
  • Motorized fiber coupled version allows an easy turn key tuning control.

High optical power

  • Output power up to 250mW for ECDL depending on technologies and up to 3W for MOPA systems.
  • Excellent quantum efficiency
  • High fiber coupling efficiency

Excellent tuning behavior

  • Large mode-hop free tuning range due to patented cavity
  • Fine tuning via piezo-actuator with a resolution better than 1MHz
  • Precise manual coarse tuning
  • Use of in-house anti-reflection coated laser diodes

Self heterododyne measurement setup are used to characterized the linewidth.

  • Linewidth down to 100kHz @ 1ms
  • Excellent side mode suppression > 50dB

Our scientific laser are turn-key:

  • Modular laser system design
  • Easy exchange of the laser diode
  • Fiber coupled and free beam versions available
  • Motorized Littman/Metcalf laser with automated wavelength scans via remote control software
  • Constant current operation modes
  • Remote control via GPIB, RS232 und USB

And also offers flexibility by configuring your ECDL with the available features:

  • Upgrade from 35dB to 60dB Optical Isolator
  • High-Frequency Current Modulation
  • Constant power operation modes
  • Multiple output
  • Frequency Lock using our Locking Modules (LB2001/LB2005 – High Frequency PI Regulator and High Frequency Synthesizer)
  • Linewidth narrowing options

We offer an excellent bench-top, combination between laser diode current, temperature controller and Piezo driver. PZ version also includes function generator. The laser driver controller offers a low noise laser current and highly stable temperature control. Remote control via USB and RS232 interface.

  • Sub μA Noise Figure have been measured
  • Excellent RIN noise figures obtained on the laser using our controllers.
