This paper introduces an experimental apparatus capable of producing cavitation fusion 
based on laser-assisted high-magnetic-field energy-intensive multifunction cavitation. 
Combining water jet, ultrasonic and magnetic field energy sources has been shown to 
increase the luminescence intensity in this system such that the threshold required for 
deuterium-tritium fusion can be exceeded. The incorporation of a laser provides a further 
improvement in emission intensity based on an increase in the internal temperature of 
bubbles. Multiphoton excitation induced by the laser irradiation raises the pressure 
generated during collisions between bubbles. Consequently, the probability of achieving 
cavitation fusion is greatly enhanced.
