High PRF HgBr Laser Life Testing.
Abstract
The major effort was to perform experimental life tests of an UV pre-ionized HgBr discharge laser, and verify noble metal (gold) electrodes for long life operation in the HgBr laser. Based on the test results of our gold-plated nickel HgBr laser there was no sign of laser deterioration at over 5,000,000 x 10 to the 6th power shots until unexpected and unnecessary blower problems forced us to interrupt the test. By operating the laser near threshold conditions gave a particularly sensitive test to chemical degradation. The previous laser discharge study and the true laser test indicated that the pinhole-free gold plated nickel was chemically inert to the HgBr. Both tests made us firmly believe that the properly designed HgBr laser can easily last 10 to the 8th power shots. For a larger laser system with further improved operating life, we suggest the addition of a HgBr2 reconstitution system.
