Abstract :
The pulsed laser deposition technique (PLD) allows for manufacturing thin layers from a wide range of materials. In our experiment we deposit Nd:YAG layers on a fused silica substrate by pulsed laser ablation from a rod target using a Q-switched laser system (Nd:YVO4) emitting 12 ns pulses at 1064 nm with a repetition rate of 20 kHz. We produced the layers in a vacuum chamber in a typical setup with the laser tilted 45° with respect to the surface normal. The ablation fluence on the target was around 4 J/cm2.
