Grating Stretcher for Ultrashort Pulses

The role of ultrashort pulses is growing in modern optical applications. For example, they can be found in the fields of laser material processing, medical imaging, optical communication and so on. Prisms and gratings are typical optical components that are used for manipulating the temporal behavior of optical pulses. In this example, a pulse stretcher consisting of two diffractive gratings are constructed and the pulse broadening effect after propagation through them is demonstrated.
