We report on the design of a compact grism-pair stretcher for a near-infrared non-collinear optical parametric chirped-pulse amplification (OPCPA) system. The grisms are produced by bonding a grating to a prism using a resin. The stretcher is capable of controlling a bandwidth of over 300 nm, which is suitable for parametric amplification of few-cycle pulses. After amplification, pulses can be compressed by the dispersion of optical glass and the residual group-delay can be compensated with an acousto-optic programmable dispersive filter (AOPDF).
