A novel external cavity laser-diode bar with a volume Bragg mirror achieves 30 W output power at 780 nm. This system demonstrates tunable wavelength emission and efficient absorption in a rubidium vapor cell.

Area of Science:

  • Laser physics and photonics.
  • Atomic spectroscopy and vapor cell technology.

Background:

  • High-power, narrow-linewidth laser diodes are crucial for various scientific applications.
  • External cavity diode lasers (ECDLs) offer wavelength tunability but often face power limitations.

Purpose of the Study:

  • To develop a high-power, narrow-linewidth, and tunable external cavity laser-diode system.
  • To demonstrate efficient absorption of the laser output by a rubidium vapor cell.

Main Methods:

  • Incorporation of a volume Bragg grating (VBG) into an external cavity laser-diode bar.
  • Characterization of output power, spectral linewidth (Full Width at Half Maximum - FWHM), and tunability.
  • Demonstration of laser radiation absorption using a rubidium vapor cell pressure-broadened with ethane.

Main Results:

  • Achieved 30 W of continuous-wave (cw) output power at 780 nm with a 20 pm (10 GHz) spectral linewidth.
  • Output power was over 90% of the free-running laser-diode bar.
  • Demonstrated wavelength tuning over a 400 pm range without spectral broadening.
  • Achieved 90% absorption of laser radiation in a 25 mm Rb vapor cell.

Conclusions:

  • The VBG-based external cavity design effectively enhances laser-diode bar performance.
  • The system provides a powerful and tunable light source suitable for applications requiring precise wavelength control.
  • Efficient absorption in a broadened rubidium vapor cell highlights potential for spectroscopic applications.
