Abstract

A new concept is introduced whereby thermal stresses generated through the pumping process are canceled by an applied force. By use of a Nd:YVO4 disk laser as a model system, significant reduction of thermal lensing and deformation is demonstrated as a function of applied pressure, and the output power 19 W TEM00 is limited only by the available pump power.

(a) Schematic of the deformed disk with back-surface cooling. The model assumes 90% absorption in a 2-mm-diameter top-hat pump profile that is incident upon a 3-mm-diameter by a 0.3-mm-thick disk with a constant temperature boundary condition on the rear surface of the disk. (b) Two-dimensional finite-element model of the deformed disk when the applied pressure is zero. (c) Two-dimensional finite-element model of a clamped disk under the same pump conditions with an applied pressure of 700 PSI (5 MPa). For clarity, the dimensions are scaled as indicated. Note the difference in the scale of the deformation between (b) and (c).
