Abstract
A laser-diode bar incorporated into an external cavity with a volume Bragg mirror produced of cw output power within a spectral linewidth (FWHM) centered at . The device output power exceeded 90% of that for the free-running laser-diode bar. The emission wavelength was tuned over a range without broadening laser spectrum width. Absorption of 90% of the laser radiation by a 25 mm vapor cell containing Rb that has been pressure broadened with 300 torr of ethane was demonstrated.
