Long-Pulsed Nd:YAG Laser and Arrhenius Equation

Usually, only one wavelength comes out in one laser device, but lasers that can express multiple wavelengths in one laser device are being released recently. V-laser (WONTECH Co. Ltd. Daejeon, Korea) combines long-pulsed KTP laser (532 nm) and long-pulsed Nd:YAG laser (1064 nm) together to achieve 532 nm and 1064 nm wavelength in one laser device (Fig. 7.1). This chapter describes a long-pulsed Nd:YAG laser and will focus on 1064 nm wavelength.
