Originální abstrakt

We present a laser system based on a tunable high-power laser diode optimized for maximum efficiency of the optical pumping process of Rb atoms. The system represents the crucial part of the HpG (hyperpolarized gasses) production process. 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. Furthermore we present the cooling system for high-power laser diode bar and the measured laser diode bar emission line too.
