Summary
We achieved continuous-wave operation of a diamond Raman laser, reaching 10.1 W output power. This demonstrates a scalable approach for wavelength and beam conversion using diamond resonators.
Area of Science:
- Optics and Photonics
- Materials Science
Background:
- Diamond Raman lasers offer potential for efficient wavelength conversion.
- Achieving high-power, continuous-wave (cw) operation is crucial for practical applications.
Purpose of the Study:
- To demonstrate cw operation of a diamond Raman laser in an external cavity configuration.
- To investigate the power scalability and efficiency of such a laser system.
Main Methods:
- Utilized a diamond gain medium within an external cavity resonator.
- Employed a pump laser to excite the Raman transition in the diamond.
Main Results:
- Achieved stable cw operation at 1240 nm.
- Demonstrated a linear increase in output power with pump power.
- Attained a maximum output power of 10.1 W with a slope efficiency of 49.7%.
Conclusions:
- The external cavity diamond Raman laser is a viable platform for high-power, cw operation.
- This approach offers a novel method for power-scalable wavelength and beam conversion.
