英文摘要	We demonstrate for the first time a sapphire-cooled Nd: glass composite assembly based on optical bonding of two thin sapphire plates to a Nd: glass slab for efficient heat removal. The distributions of temperature, stress, depolarization loss, and wavefront aberration were obtained by finite element analysis. The simulation results were verified experimentally. Although the heat generation rate was 4.5 W/cm(3), the temperature increase was within 5.7 degrees C at the center of the sapphire surface, and the whole wavefront aberration was 1.21 lambda (lambda = 1053 nm). This demonstration opens up a viable path toward novel repetition rate Nd: glass laser amplifier designs with efficient double-sided room-temperature heat sinking on both sides of the slab.
