Water molecules have strong absorption of lasers in the 1.3μm band, so the 1.3μm laser have a wide range of applications in clinical medical hemostasis, laser cosmetic, skin diseases treatment, and dental treatment. The energy level transition in erbium-doped crystals is the main way to generate the 1.3μm laser. The working substance of Nd:YAP laser is ytterbium-doped yttrium aluminate crystal, It has a water absorption rate of 2.700832 and a shallow penetration depth of about 1.5 mm. The Nd:YAP laser is more suitable for the treatment of superficial hemangiomas.
The main components of device are:
Nd:YAP crystal has large optomechanical coefficient, large transition cross section, high thermal conductivity and polarization output. It has obvious advantages for high-power 1.3μm laser. The crystal used in the structure diagram is a long-term storage of long crystal rods which are made by spheronization, chopping, polishing, coating, etc.
