Abstract
The technical elements for table-top chirped-pulse amplification (CPA) lasers to generate ultrashort high-intensity pulse light, that is, mode-locked oscillators for femtosecond pulse generation, pulse stretcher and compressor for CPA, amplifiers to generate high energy, and compensation of spectra-narrowing and phase distorsion, are reviewed. Feasibility of table-top petawatt lasers is also briefly discussed.
