✦ Synopsis
Output beam spatial properties of a dual wavelength CW
DPSS laser have been studied using the thermal lens (photothermal)
effect. In employing the Z-scan technique both the
steady-state and time-dependent thermal lens signal as a function
of sample position could be examined simultaneously. The influence
of sample thickness and laser output power upon obtained spatial
properties of incident beam is studied. It is shown, that both the
steady state and the transient photothermal signal provide
comparable results.
