In the most common sort of diode pumped solid state laser (DPSSL), an  808nm wavelength infrared GaAlAs laser diode pumps a neodymium-doped yttrium aluminium garnet (Nd:YAG) crystal which produces 1064nm wavelength laser light from the main spectral transition of neodymium ion. This light is then frequency doubled using a KTP crystal, producing 532 nm light. Green DPSSLs are usually around 20% efficient
