PTC Optical Instrument brings new solution to Laser Photonics

The 18th Laser World Photonics China successfully concluded at the Shanghai New International Expo Center. During this exhibition, local Chinese and international exhibitors displayed many advanced core solutions in five fields:
Laser Intelligent Manufacturing, Laser and Optoelectronics, Inspection and Quality Control, Optics and Optical Manufacturing, and Infrared Technology and Applications.

Laser power continues to increase, high-power lasers are gradually popularized, and the ultrafast laser market is expanding rapidly. As the core of solid lasers, laser crystals have important and extensive applications in military and civilian fields such as laser precision processing, laser weapons, photoelectric countermeasures, laser medical treatment and many others.

Laser crystals have the characteristics of high thermal conductivity and optical anisotropy. Cd:YAG is a new substrate and window material for ultraviolet and infrared optical devices. During the growth process of YAG single crystal, due to the temperature gradient between the crystal and the melt, a certain amount of residual stress will still remain inside the crystal even after a certain annealing process.

In order to observe and analyze the stress of crystals more intuitively, PTC Optical Instrument has developed a series of Polariscopes. These Polariscopes help technicians to quickly observe stress distribution , measure optical retardation in crystal products.
