FIG. 1.

(Color online) Geometry of the Brewster-cut Ti:sapphire crystal used in the finite element analysis. Dimensions are in meters.

FIG. 2.

(Color online) Schematic of the variable repetition rate chirped pulse amplifier used in these experiments. The Ti:sapphire crystal is cooled to (unpumped) using liquid nitrogen.

Image of FIG. 3.
FIG. 3.

(Color online) Experimentally measured optical path difference (green circles) as a function of pump power for single end pumping. The squares, triangles, and stars are the predicted OPD using fixed boundary temperatures of 113, 103, and , respectively.

FIG. 6.

(Color online) Comparison of experimentally measured thermal lens power (squares) against numerically predicted values using finite element analysis (circles) and an analytical expression for thermal lensing derived by Feldman et al. 18 (triangles).

Image of FIG. 7.
FIG. 7.

(Color online) measurement for an uncompressed amplified beam with an average power of at repetition rate in the (a) vertical and (b) horizontal axes. Inset in (b) is the CCD image of the amplified beam spot.

Image of FIG. 8.
FIG. 8.

(Color online) Thermally induced optical path difference vs (a) crystal length and (b) crystal radius for (left axis) and (right axis). The computed OPD along the horizontal axis of the crystal is shown as solid points; along the vertical axis, as hollow points. The lines are guides to the eye.
