Profile
rail OCM 650, 500 mm
The main components of the experimental systems are the
optical rails OCM 650. They are manufactured
distortion-free and are of thermally stabilized
aluminium. The surface is electro-polished and black
anodized. Because of the precise manufacturing, the
smoothness deviation is less than 25 µm/m and the
deviation of the symmetry axis of the rail is less than
10 µm/m, thus maintaining the optical axis during
displacement of the carrier.
The rail has a dovetail like profile. Gear racks can be
inserted and fixed into the slots. The profile rails are
available at various lengths up to 2 m.

Mounting
plate OCM 650-50 including carrier 20 mm
Mounting plates are used to hold optical mounts. A
characteristic feature of the mounting plates is the
“click” mechanism of the inserts based on spring loaded
spheres. Snapping in the groove of the inserted click
mount, the optical element is kept in an exact position.
On the other hand, the system allows a quick and easy
change of the mounted inserts.
The mounting plates are made out of special anodized
aluminum. Mounted onto the carrier 20 mm, the mounting
plates can be placed onto an optical rail.

PIN Si
Photo detector BPX 61 complete with housing
In a housing a PIN Si photo detector is mounted. Via a
BNC connection the signal is fed to the respective
pre-amplifier or oscilloscope. The module is clicked
into the mounting plate, where it is fixed by means of
three separate spring loaded balls which snap into the
groove of the detector housing.

LFS-01 HeNe
Laser frequency stabilizer
The task of frequency stabilisation is firstly to
determine the deviation from a fixed centre frequency of
the laser. In this set-up, the intensity difference of
the emitted orthogonally polarised laser modes provides
this information. In case the difference is zero, both
modes are located symmetrically to the centre frequency.
To obtain this situation, the length of the optical
resonator must be controlled by means of a heating coil.
For best results, a proportional and integral (PI)
controller is applied. On a TFT display, the information
of the stabilisation state is displayed. To train the
operation of a PI controller different parameters can be
entered via the buttons of the micro-processo

Polarisation analyser with mounting plate and rotation
assembly
In a rotational ring mount with a 360°, scale a
polariser is assembled. By turning the ring, the
transmitted intensity is monitored. In case the incident
light is polarized, a minimum intensity occurs
indicating that the polariser is adjusted 90° with
respect to the polarisation direction of the incident
light.

Two mode HeNe laser
Due to safety reasons with respect to the high voltage
supply of the HeNe-laser tube, the set-up is enclosed by
an acrylic box. The length of the tube is designed in
such a way that the laser can only emit two transverse
modes. Due to the inner laser dynamic, these modes are
perpendicular polarized to each other. To change the
length of the resonator for stabilisation purposes, a
bifilar arranged heater coil is applied to the tube.

Mode separator and photodiode
To separate two orthogonal modes in order to determine
the intensity of each one, a polarising beam splitter
cube is used. Behind the cube, two photo detectors are
attached under an angle of 90° to each other to measure
the intensity of each mode.
