Narrowband tuneable laser, low-noise fiber amplifier, low-noise electrical signal amplifiers, GHz signal generator

The equipment is being used for experiments in quantum optomechanics and quantum optics. The output of the narrow-band and tuneable 1560 nm laser will be split into two parts - one part will be used to lock the laser to a high-finesse optical cavity, another part will be sent through an electro-optical intensity amplifier and then amplified in a low-noise fiber amplifier. This strong beam will then be used to trap dielectric test particles for experiments on optomechanics, and the weaker beam will be sent through a GHz electro-optic modulator to generate a sideband that is locked to a high-finesse optical cavity. For this, we will use the GHz signal generator. The low-noise amplifiers will be used for improving the signal from photodiodes that are used to detect the motion of the trapped particle.

Access to the equipment is possible in accordance with the availability of the equipment and in agreement with the equipment administrator. Before starting work, the administrator must be informed about the procedures and operations for which the equipment will be used. Work with the equipment is possible only under the supervision of the equipment administrator, in the FMF premises and for procedures and operations that have been previously agreed upon. If the equipment administrator determines that the intended use does not comply with the instructions for use of the equipment and could damage or destroy the equipment, the equipment administrator may refuse access to the equipment.
