Abstract

We demonstrate the use of a plasma mirror to obtain 60-fs 10-TW laser pulses with a temporal contrast of 10⁸ on a nanosecond time scale and 10⁶ on a picosecond time scale, and we use these high-contrast pulses to generate high harmonics by nonlinear reflection on a plasma with a steep electronic density gradient. Well-collimated harmonics up to 20th order are observed for a laser intensity of ≈3 × 10¹⁷ W/cm², whereas no harmonics are obtained without the plasma mirror.
