Laser Room

Brief Description

The laser room is set up for the laser ultrasound non-destructive evaluation technique, which is contactless and couplant-free compared to conventional PZT ultrasonic transducers. There are a generation laser (Class 4) and a detection laser (Class 3R) in the room. The lasers are mounted on motorised stages to achieve optical scanning.

Laser safety

Both the Class 4 and Class 3R lasers can cause safety issues such as eye damage. The laser safety training can be found here. The risk assessment can be found here. Please sign in the hard copy of the rish assessment in the lab. Safety goggles, etc.
