Pulse Compression for Generating Femtosecond Pulsed Laser Beams Using an Externally Controlled Compression Configuration
M. Hemdan, S.I.H. Elnaby, A.M. Abd-Rabou and A.F. Hassan
A spectral broadened laser pulse is injected into a combination of four prisms divided into two symmetric sets between which a slab sandwiched between two matrix formed electrodes with spatial controllable electric field is inserted. Through varying the electric field the phases of the spectral components are equalized and the pulse is temporally compressed at any desired location without any mechanical motion of the component comprising the compressor.
