A 2.4 GHz Kerr-lens mode-locked laser, employing Yb:Y2O3 ceramic as the gain medium, has been fully integrated into a compact 61 mL volume. By optimizing the pump structure, all optical components of the laser are confined within a 34 × 78 mm2 area, enabling effective temperature control. Owing to the temperature control, the repetition-rate drift of the laser in free-running mode can be as low as ∼10−8 with a timing jitter of 13 fs.
