Abstract
To inexpensively and in a simple configuration provide a solid laser amplifier and a solid laser unit capable of generating a high output and high quality laser beam, the unit includes a solid laser medium 5A containing active solid media; a flow tube 14 or the like allowing a cooling medium 24 for cooling the solid laser medium 5A; and a laser array 12 so controlled in temperature as to emit an excitation light 9 for exciting the solid laser medium 5A, the wavelength of which lies within the absorption spectra of a solid laser medium 5A yet does not coincide with that of the absorption spectrum peak of a solid laser medium 5A.
