Nd:YAG laser is one of solid state laser using Nd:YAG (Neodymium-doped aluminium garnet) crystal as its energy medium and it radiate through the wavelength of 1064nm and 532nm. Q-switch is a technique to enable laser generate high energy pulse (mega watt) in an extremely short time (Nano second). KTP is a nonlinear optical materual which is commonly used for frequency doubling diode pumped solid-state lasers such as Nd:YAG and other neodymium-doped lasers. Dual chamber of dual rod supports high speed and high power of Andy laser in compact size.
