NANOSECOND-TO-PICOSECOND PULSE-COMPRESSION WITH FIBER GRATINGS IN A COMPACT FIBER-BASED CHIRPED-PULSE-AMPLIFICATION SYSTEM

A chirped, 12-cm-long fiber Bragg grating with 10-nm spectral bandwidt h was employed in place of a conventional diffraction grating pair com pressor in a compact fiber-based high-energy chirped-pulse-amplificati on system. Initial nanosecond chirped pulses from a fast-tuned laser d iode were compressed to produce 1.9-ps-long, 300-nJ pulses. (C) 1996 O ptical Society of America
