If we select substrate temperature, laser power and the scan speed properly, we can get good crystallization. It is useful to the fabrication of SOI devices.

适当选择衬底温度、激光功率和扫描速度可望获得良好的结晶，它对SO I器件的制作是有意义的。

To record over an existing recording, the amorphous spots are reheated by the recording laser to a temperature that allows them to recrystallise.

In their latest experiment, Dr Sullivan and his colleagues painted the blades of a rotor with both temperature-and pressure-sensing paints, shone laser light on to them, and mapped out the temperatures and pressures as the blades whirred around as fast as 14, 000 rotations per minute.

The polymers return to a pre-defined shape when heated to a certain temperature, and, when damage is detected, an infrared laser sends light through the network to the damaged area, triggers the shape-memory, and commands the area to repair the crack or tear -- regaining up to 96 percent of its original strength.
