The external cavity quantum cascade laser with this design may operate very stable due to its low dependences on voltage and temperature, he says.

“应用这种设计的外腔式量子级联激光器能够非常稳定地运行，这得益于对电压和温度的弱依赖关系，”他说。

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.
