METHOD OF TESTING OPTICAL MATERIALS FOR MICROINHOMOGENEITIES |
| 摘要 |
Solid optical materials such as glass which are to be used in laser systems may fail catastrophically due to the presence of microinhomogeneities. These microinhomogeneities are locatable by exposing the material to a laser pulse which preferably has a pulse duration of approximately 0.1 to 10 microseconds.
