Summary
We demonstrated a single-frequency, continuous-wave, optically pumped semiconductor laser (OPSL) using injection-locking. This technique boosted laser output power beyond its free-running state, achieving over 9 W at 1015 nm.
Area of Science:
- Optics and Photonics
- Semiconductor Lasers
Background:
- Optically pumped semiconductor lasers (OPSLs) are crucial for various applications.
- Achieving high output power and single-frequency operation is a key challenge.
Purpose of the Study:
- To demonstrate a single-frequency, continuous-wave OPSL using injection-locking.
- To investigate the impact of key parameters on laser performance.
Main Methods:
- Utilized an injection-locking technique to stabilize OPSL output.
- Systematically varied output coupling, injection power, and injection wavelength.
- Employed a master laser for injection.
Main Results:
- Achieved single-frequency, continuous-wave operation.
- Demonstrated that injection-locking can enhance output power compared to free-running.
- Obtained over 9 W of output power at 1015 nm with 1.5 W of injection power.
Conclusions:
- Injection-locking is an effective method for improving OPSL performance.
- Optimized parameters are critical for maximizing output power.
- The demonstrated OPSL shows potential for high-power, single-frequency applications.
