Paper Abstract

An adaptive negative thermal lens that compensates for the power- dependent positive thermal lens in a transversally diode-pumped Nd:YAG laser rod is presented. The compensating (negative) lens is generated in a thin layer of liquid. We demonstrate that the proposed technique leads to a reduction of the thermal lens by more than an order of magnitude.
