Abstract

In this paper,the output power of second harmonic versus the focus length of the lens and the position of extracavity frequency doubling crystal has been investigated by using a KTP crystal in 1.0795 μm TEM00 mode Nd:YAP laser. The experimental results show that here are a optimum focusing and a optimum positioil of the crystal to obtain the maximum output power of the second harmonic.
