Abstract:

The report discusses surface and particulate damage to laser glass by high power laser pulses. Surface damage is studied through high speed holography. Holograms of damaged samples are taken within a few hundred nanoseconds after damage. The plasmas and acoustic disturbances associated with damage and visible in these holograms are analyzed in detail. The possibility of eliminating damaging particles from laser glass is examined in a theoretical and experimental investigation. Melting of glass under reduced partial pressure of oxygen in platinum is presented as a method for accomplishing this elimination. Also discussed in this report is the design of a high power, high energy, TEMoo mode laser to be used in damage studies.
