Researchers achieved high-power self-mode-locked operation in a ytterbium-doped yttrium oxide (Yb:Y2O3) ceramic laser. This breakthrough, without extra cavity elements, yielded 2.7 W output power and marks the first self-mode-locked ceramic laser.
Area of Science:
- Laser Physics
- Materials Science
- Optics
Background:
- Ceramic lasers offer advantages in power handling and scalability.
- Mode-locking is crucial for generating ultrashort laser pulses.
Purpose of the Study:
- To demonstrate self-mode-locking in a Yb:Y2O3 ceramic laser.
- To investigate the underlying mechanisms of self-mode-locking in this material.
Main Methods:
- Experimental setup of a high-power Yb:Y2O3 ceramic laser.
- Achieved self-started continuous-wave (cw) mode-locking without additional optical elements.
- Performed numerical studies to understand the mode-locking dynamics.
Main Results:
- Successfully demonstrated self-mode-locking in the Yb:Y2O3 ceramic laser.
- Achieved a maximum output power of 2.7 W.
- Obtained a pulse duration of 1.1 picoseconds (ps).
Conclusions:
- The first self-mode-locked ceramic laser was realized.
- Diffraction loss from thermal aberrations and Kerr self-focusing drive the mode-locking mechanism.
- Yb:Y2O3 ceramic is a promising gain medium for high-power, ultrashort pulse lasers.
