Abstract
Abstract Laser device of the neodymium doped glass disc array type. The discs are spaced apart from one another and are immersed in a liquid whose refractive index is equal, for the emission wavelength of the laser, to the refractive index of the glass forming the discs. The disc inclination angle with respect to the disc alignment direction can take any desired value. To pump the discs in the whole volume thereof, the spacing is given a value higher than a predetermined minimal value and an inclination angle of 45* is selected. The immersion liquid is a mixture of a brominated saturated acyclic hydrocarbon and a saturated acyclic alcohol.
