Summary 

									
								

							

						

						
Aiming to realize the newly actuator without any electric cable, the use of laser-induced water vaper bubble has been proposed. We have performed the principle confirmation experiment by using carbon powder suspension for working liquid and an infrared Laser Diode (LD) of 970nm wavelength. As the 970nm LD light is not absorbed by water but carbon, the water of the working liquid could be vaporized by heated carbon. Under the condition of laser peak power of 180W and pulse duration of 2ms, the reciprocating motions of the stainless steel rod of 2.3mm diameter have been observed.
