Laser Spectroscopy Solution
CoSy
The CoSy system is a versatile tool for Doppler-free absorption saturation spectroscopy. This permits a generation of extremely precise defined wavelength standards, which can be used for highly precise stabilization of tunable lasers.
• The CoSy head contains the setup for the Doppler-free saturation spectroscopy. It is available with Cesium-, Rubidium- or Potassium cells (other cells on request)
• The CoSy head is controlled by the power supply and control electronics CoSyControl.
Performance parameters
| Glass cell filled with one of the following elements | Rubidium (mixture of 85Rb and 87Rb) |
| Potassium(mixture of 39K and 41K) | |
| Caesium (133Cs) | |
| Other cells on request | |
| Recommended optical input power | <1mW, depends on used element |
| Size of free beam | <3mm diam |
| Polarization of free beam | Perpendicular to table top |
| Gain of the photo detector amplifiers | Adjustable via range switch (coarse) |
| And trim potentiometer (fine) | |
| Output level | Max. 10Vpp |
| Set temperature of the glass cell | Adjustable via trim potentiometer in the range of 20 to 40℃(no cooling) |
| Optional AC or DC magnetic field | Magnetic flux density adjustable |
| Maximum current 0.1 Ampere |
