Module A: Laserdiode module DIMO 100 is mounted into the
XY-adjustment holder. The adjustment holder allows the sensitive
adjustment of the laser in the x and y direction to ensure the
correct directional orientation with regard to the optical axis of
the setup. The module contains a laser diode with an output power
of 30 mW at a wave length of 820 nm (wave length is subject to
certain deviations within the range of ± 5 nm ). The integrated
Peltier element allows temperature control in the rangeof 15 to 40
°C by means of the control unit LDC-01.
Module B: Microscope objective screwed into a mounting plate on
a carrier collimates the laser diode radiation.
Module C: Optics for coupling the laser diode radiation into
fibre. The microscope objective can be adjusted in the directions x
and y and in two orthogonal angles.
Module D: Fibre holder. The fibre is put into the groove of the
holder and fixed in its position by means of a magnet. The fibre
holder is mounted on translation stage to enable a precise
adjustment of the fibre position with respect to the focused laser
Module E: Hinged joint angle connector onto which the second
fibre holder has been screwed for angle resolved measurements, for
example the numerical aperture of the fibre or the intensity
distribution of the laser diode.
Module F: 100 m monomode fibre with a core diameter of 5 µm.
Module G: PIN-Si photo diode mounted in a housing with click
mechanism and BNC socket. Mounting plate on a carrier.
Module H: Laser diode controller providing all voltage and
currents needed for the safe use of the laser diode and the
Peltier-cooler. Built-in amplifier for Module G and modulator for
the injection current of the laser diode.
