NEODYMIUM DOPED PHOSPHATE LASER GLASS HAVING LOW EXPANSION AND HIGH GAIN

摘要

PURPOSE: To obtain Nd-doped phosphate laser glass with low expansion and high gain, having a high inducted emission coefficient, capable of oscillating highly repeatedly, having a glass composition of low expansion. ;CONSTITUTION: The characteristic of this Nd-doped phosphate laser glass having low expansion and high gain is that the glass has a high content of a glass forming oxide comprising 68-86 cat % (cation %) of a glass forming oxide containing 56-74 cat % of PO_2.5, 10-14 cat % of a modified oxide composed of an alkali oxide and an alkaline earth oxide and 0.5-19 cat % of a rare earth oxide containing 0.5-5 cat % of Nd_1.5.;COPYRIGHT: (C)1996,JPO
