The system represents the first and crucial part of the HpG (hyperpolarized gasses) production process. It was designed for laboratory purposes where the expensive and complicated Ti:Sa laser is justified because of its variability, narrow linewidth and easy tuning of the wavelength. The system consists of a modified commercial Ti:Sa laser pumped by a Nd:YAG laser, beam-forming and polarizing optics, and heated interaction cell attached to a vacuum manifold and gas containers placed in homogeneous magnetic field generated by a set of Helmholz coils. Furthermore we describe another laser system based on a high power semiconductor laser. It is designed to operate in medical and industrial applications to come. We concentrated on the lased diode emission linewidth reduction because of the efficiency of the optical pumping process.
