Abstract:

This paper analyzes the requirements imposed on laser glasses intended for the fabrication of rod-shaped and large disk-shaped active elements with a large aperture for generators and heavy-duty radiation amplifiers. Quantitative data are presented concerning the maximum achievable values of the functionally important basic characteristics of domestically produced neodymium phosphate glasses and the copper-oxide-doped glasses from which absorbing shells (cladding) are fabricated that suppress superluminescence and stray lasing in disk-shaped active elements.

Keywords:

neodymium and copper-bearing phosphate glasses, active elements, absorbing shells, laser, radiation amplifier, quantum yield and luminescence lifetime, birefringence, inactive radiation absorption, glass radiation resistance
