Temperature dependency of luminescence from laser-produced cavitation bubbles

Single laser-produced bubbles emit short light pulses in the collapse phase. This phenomenon is called single-cavitation bubble luminescence (SCBL) in analogy to single-bubble sonoluminescence (SBSL) where the bubbles levitate in an acoustic field. Laser bubbles are produced using a Q-switched Nd:YA...

Description
Summary:Single laser-produced bubbles emit short light pulses in the collapse phase. This phenomenon is called single-cavitation bubble luminescence (SCBL) in analogy to single-bubble sonoluminescence (SBSL) where the bubbles levitate in an acoustic field. Laser bubbles are produced using a Q-switched Nd:YAG laser. The laser beam is focused with an aberration-minimized lens system into a temperature controlled cuvette filled with bidistilled water. A photomultiplier collects the light emitted in the collapse phase of the bubble. Bubble size is monitored with a hydrophone. As laser-produced bubbles are bigger in size than their acoustically driven counterparts, they emit stronger light pulses. The light energy per pulse in dependence on bubble size is reported. SBSL shows a strong dependency on temperature and a similar behavior is expected for SCBL.
