Sensitization of neodymium ion luminescence by chromium ions in a Gd/sub 3/Ga/sub 5/O/sub 12/ crystal
An investigation is reported of the spectral, luminescence, and lasing properties of a Gd/sub 3/Ga/sub 5/O/sub 12/ crystal activated with chromium and neodymium ions. The high efficiency of the energy transfer process from chromium to neodymium ions is demonstrated. For example, the probability of an elementary Cr/sup 3 +/--Nd/sup 3 +/ interaction event in a Gd/sub 3/Ga/sub 5/O/sub 12/ crystal was 12 times higher than that in a Y/sub 3/Al/sub 5/O/sub 12/ crystal. It was found that sensitization of neodymium ion luminescence by chromium ions can increase severalfold the energy characteristics of cw and pulsed neodymium lasers. An investigation of the free-lasing parameters shows that the ultimate differential lasing efficiency of neodymium in a Gd/sub 3/Ga/sub 5/O/sub 12/:Cr:Nd crystal is 3.6 times higher than that for a YAG:Nd crystal under comparable conditions.
