1）Intra-cavity EOM Adjustment：Adjusts the repetition rate in the range of 10 kHz - 1 MHz without changing the power. For the high-energy version, the range is 10 kHz - 100 kHz, with linear variation in single-pulse energy.

2）Extra-cavity EOM Adjustment：Supports tunable repetition rates from single-shot to 1 MHz, maintaining constant single pulse energy, while the average power varies linearly with the repetition rate.
