We achieved high photon-conversion efficiency in a diode-pumped continuous-wave (cw) Raman laser using hydrogen gas. This novel Raman laser system reached 66% efficiency, producing significant Stokes power at 1180 nm.

Area of Science:

Optics and Photonics
Laser Physics
Nonlinear Optics

Background:

Continuous-wave (cw) Raman lasers offer potential for wavelength conversion.
Achieving high photon-conversion efficiency is crucial for practical applications.
Existing theories may not fully capture performance under high power.

Purpose of the Study:

To demonstrate a diode-pumped cw Raman laser in hydrogen gas.
To achieve high photon-conversion efficiency.
To investigate deviations from theory at high Stokes power.

Main Methods:

Utilized an injection-locked diode laser operating at 792 nm as the pump source.
Employed hydrogen gas as the Raman medium.
Characterized the output power and wavelength of the Stokes laser.

Main Results:

Achieved a photon-conversion efficiency of (66+/-8)%.
Generated a Stokes laser output at 1180 nm with a peak power of approximately 16 mW.
Observed deviations from theoretical predictions, attributed to the thermal-lensing effect.

Conclusions:

Demonstrated a highly efficient diode-pumped cw Raman laser.
The high Stokes power suggests the potential for this technology in various applications.
Thermal-lensing effects in the Raman gas significantly influence laser performance at high power levels.
