The present disclosure relates to a broadband optical parametric chirped pulse amplifier insensitive to temperature comprises the first pulsed laser, the second pulsed laser, a pulse stretcher and a periodically poled nonlinear crystal. Via the proper arrangement of the non-collinear angles between the transmission directions of the signal light, the pump light and the idler light, to simultaneously satisfy the angular relationship required for constructing the non-collinear phase-matching configuration insensitive to wavelength and that required for constructing the non-collinear phase-matching configuration insensitive to temperature, the optical parametric chirped pulse amplifier not only can realize a broadband parametric amplification of the signal light (insensitive to wavelength), but also can effectively alleviate the phase mismatch in nonlinear crystal resulted from the excessively high local temperature (insensitive to temperature).
