7 June 1996 Efficient all-solid state 213-nm laser source for microlithography
Author Affiliations +
We describe a 0.4W average power at maximum, frequency-quintupled Q-switched Nd:YAG laser at a repetition rate of 7 kHz, which is a potential light source for next generation microlithography. Calculated results for the conversion efficiencies considering pump depletion will be discussed. Our results allow to foresee further scaling up 213 nm power up to the 1W level by increasing the fundamental power.
