Pressure tuning of thermal lensing for high-power scaling.
A new concept is introduced whereby thermal stresses generated through the pumping process are canceled by an applied force. By use of a Nd:YVO(4) 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 TEM(00)) is limited only by the available pump power.
