RF Modulation Spectroscopy Setup

Spectroscopy Setup for Pound-Drever-Hall stabilization


The RF Modulation Spectroscopy Setup is a precise prealigned, fiber coupled, spectroscopic platform. With its help it is possible to stabilize external cavity diode laser also as DFB laser systems on top of line to atomic references via fast laser modulation.


Technical Details

The RF Modulation Spectroscopy Setup is able to generate a locking error signal on a the top of the line of an atomic reference vapor spectrum. This error signal enables to stabilize the wavelength of the emitted laser radiation in combination with the LB2001 and LB2005 and results in a frequency stabilized narrow linewidth of tunable laser systems.

Vapor cells and wavelenghts

  • designed for different vapor cells and references
  • wavelenght from 400nm - 1650nm

Gascell heating

  • vapor cell heating (optional)
  • recommended for alcali atoms with low vapor pressure (Potassium, etc.)


  • precisely prealigned
  • intuitive handling

Fiber Coupling

  • FC/APC connector (optional)

Excellent signal to power performance

  • detects lowest laser radiation
  • selectable conversion of  photodiode


  • portable device

High detector bandwidth

  • decector bandwidth up to 20MHz
