Summary
A new high-power continuous-wave coherent light source at 253.7 nm was developed using a Ytterbium-doped Yttrium Aluminum Garnet (Yb:YAG) disk laser. This laser system enables stable output powers up to 750 mW for advanced spectroscopic applications.
Area of Science:
- Laser Physics
- Quantum Optics
- Spectroscopy
Background:
- Development of stable, high-power coherent light sources is crucial for advanced spectroscopic techniques.
- Existing light sources may lack the required power or stability at specific ultraviolet (UV) wavelengths.
Purpose of the Study:
- To describe a novel high-power continuous-wave (CW) coherent light source operating at 253.7 nm.
- To demonstrate the utility of this light source for high-resolution spectroscopy.
Main Methods:
- Utilized a solid-state Ytterbium-doped Yttrium Aluminum Garnet (Yb:YAG) disk laser.
- Employed two successive frequency doubling stages to achieve the target wavelength.
- Characterized the output power stability and spectral properties.
Main Results:
- Achieved a stable output power of up to 750 mW at 253.7 nm.
- Successfully demonstrated spectroscopy of the mercury 6 (1)S(0)-6 (3)P(1) transition using the developed light source.
Conclusions:
- The developed Yb:YAG disk laser system provides a powerful and stable UV coherent light source.
- This system is well-suited for precise spectroscopic measurements, including atomic transitions.
