Temperature effects on the behavior of laser-induced bubble in water near the surface of Cu target are investigated experimentally by means of a fiber-coupling optical beam deflection technique (OBD).The maximum and minimum bubble radii as well as the period and velocity of contracting-expanding of the bubble are determined according to the characteristic signals.The tests of cavitation bubble are performed by using distill water at different temperatures from freezing point(0 ℃) to near boiling...
