    AnnotationWe present an extended cavity laser system based on a tunable high-power laser diode optimized for maximum efficiency of the optical pumping process of Rb atoms. The application of the laser system is oriented to employment in an experimental arrangement for production of hyperpolarized gasses (HpG), namely Xenon. It is designed to operate in medical and industrial applications to come. We concentrated on the laser diode emission linewidth reduction because of the efficiency of the optical pumping process. The emission linewidth was reduced approximately from 1 THz to 69 GHz with only half of the total optical power loss and quadruple increase of the power spectral density at the wavelength of desire.
