Preface to Special Issue on Forefront of Ultrahigh Intensity Laser Development Using Nonlinear Optical Crystals

Abstract

In this special issue, present status and future prospects of Optical Parametric Chirped Pulse Amplification (OPCPA) are reviewed by the leading laboratories in China, UK, Czech and Japan. This Preface briefly reviews several approaches toward realizing 10 PW ~ 100 PW power, including Ti:sapphire laser, OPCPA, and other approaches such as coherent beam combining (CBC) and Compression after Compressor Approach (CafCA).
