Description

Single-Pass AOM Clusters are versatile opto-mechanical units that enable fixed frequency detuning, fast switching and intensity modulation of laser light . These setups can be combined with beam splitters, monitor diodes, shutters and other established multicube™ components.

Optical Setup
The input light enters the system via a PM fiber cable. A photodiode positioned immediately after the input port enables continuous monitoring of the input laser power. The acousto-optic modulator (AOM) diffracts the incident light and induces a frequency shift in the MHz range. The diffracted light can be used for 1 to x output ports or can be combined with other Multicube Systems. 
 
Acousto-optic Modulators
The acousto-optic modulators form the centerpiece of all Integrated AOM Systems. We integrate purchased AOMs (e.g. MT-Series from AA Optoelectronics, AOMO-Series from Gooch & Housego as well as corresponding modulators from other manufacturers with a similar form factor). The tunability and the efficiency of the system are determined by the diffraction efficiency of the respective AOM. 
 
Fiber Couplers
A fundamental component of Integrated AOM Systems is the Laser Beam Coupler, which is used to collimate the radiation at the input of the opto-mechanical unit. It is also employed to couple the output radiation back into a polarization-maintaining fiber cable. The stability of the Integrated AOM System is determined by the stability of the Laser Beam Coupler.
