Abstract: | A simple derivation, which relates the thermal lens focal length in solid state lasers to pump power and a method for direct
estimation of thermal lens focal length, is reported. This method is applicable to any type of stable resonator. The method
is used for the measurement of the thermal lens focal length with an accuracy of 8% in an axially pumped microchip laser.
The variation of focal length with pump power is also measured. |
