1. General
The OAFP and OAGP optical attenuators are used to attenuate the output of various laser and amplifier sources with 10^3 dynamic range. The OAGP model is based on a simple scheme with a Glan prism ensuring high throughput and simple operation.
The OAFP version is specifically developed for ultrashort pulses with duration of less than 100 fs and utilizes a thin zero-order half-wave plate and two mirror polarizers that allow selection of input radiation according to polarization. The unit introduces virtually no dispersion to the input pulse, a major factor in many femtosecond applications.
Both the OAFP and the OAGP can be motorized and USB-controlled for further seamless integration into your setup. See Modifications for details. The system can also be integrated in other products from our family, like femtosecond lasers and amplifiers.
