Comparative study of high power diode-pumped Nd:GdVO4 and Nd:YVO4 lasers

In this study we compared the performance of in-band diode-pumped Nd:YVO₄ and Nd:GdVO₄ lasers. The lasers were analyzed for both their output powers and their thermal lens dioptric powers. Despite both lasers achieving >10W of average output power, the Nd:YVO₄ crystal exhibited stronger thermal lensing compared to the Nd:GdVO₄, which was attributed to its lower thermal conductivity.
