Segmented High Average Power Ho(3+) : YLF Laser
Abstract
A novel technique for building disk lasers is described which offers considerable simplification of their design. The laser disk is bonded into a glass Holding ring with Teflon FEP film. Tapering the mating surfaces of the disk and disk holder not only makes assembly possible but also minimizes the effects of different thermal expansion coefficients of the two pieces. Calculations of the maximum fabrication errors and bonding pressures indicated that the technique was, indeed, feasible. A Ho(3+):LiYF4 disk was bonded into a glass slide, verifying these preliminary calculations. Measurements of the transmittance of the bonded surfaces indicate that a very low loss interface is formed due to the nearly equal indicies of refraction of the Teflon film and glass or LiYF4.
