利用高脉冲重复频率激光（1 kHz）在金属表面上演示了激光等离子体中的高次谐波产生。发现如果使用足够厚的块状靶，则热传导足以防止在该重复率下金属等离子体羽流产生的任何恶化。在适当的条件下，谐波产额被发现保持稳定的> 105激光射击，而不需要移动的目标。高重复率允许短和长的电子轨迹被清楚地确定在谐波产生期间从金属等离子体。
High-order harmonic generation in laser-produced plasma was demonstrated on metal surfaces using a high pulse repetition rate laser (1 kHz). It was found that if sufficiently thick bulk targets were used thermal conduction was sufficient to prevent any deterioration in the metal plasma plume production at this repetition rate. Under appropriate conditions harmonic yields were found to remain stable for >105laser shots without the need to move the target. The high repetition rate allowed both short and long electron trajectories to be clearly identified during harmonic generation from the metal plasmas.
