On Femtosecond Laser

Grating is a common optical dispersion component. It is an object or device that has a spatial periodic distribution within a certain spatial range and can amplitude modulation or (and) position phase modulation of electromagnetic waves according to certain laws. According to the usage, the grating can be divided into transmission gratings and reflection gratings, and re...

Off-axis parabolic mirror (OAP) can get beam focused or collimated at certain angles, and infinite focus is possible, too. The total reflection design eliminates the absorption loss, chromatic aberration, dispersion and phase delay due to transmissive optical element. Sometimes there is a small hole at a specific point of the OAF, which enables the coaxial transmission o...

A Glan-Taylor prisms is an air-spaced prism, which is used as a polarizer or polarizing beam splitter. It is one of the most common types of modern polarizing prism. It was first described by Archard and Taylor in 1948. The prism is made of two right-angled prisms of (or sometimes other birefringent materials) which are separated on their long faces with an air gap. The...
