Which mode lasing increases when pulsed laser's resonator shortens?

💡 Explanation

Shorter resonator length will increase longitudinal mode frequency separation because the longitudinal modes are determined by the cavity length and Fabry-Pérot effect. Larger separation occurs, therefore higher frequency modes lase rather than lower frequency modes dominating due to gain bandwidth.
