exclusive inclusion such that a process method article or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process method article or apparatus an element proceeded by u201c comprises a u201d does not without more constraints preclude the existence of additional identical elements in the process method article or apparatus that comprises the element in the first embodiment of the present invention as shown in fig1 a and fig1 b the phototherapy apparatus 100 is in the form of a phototherapy massage wand comprising an optical head 102 a synthetic jet cooler 112 and a handle 120 the optical head 102 holds a laser or light emitting diode led light source 104 and a rolling massage ball 108 the massage ball 108 may rotate freely in all directions a 360 u00b0 freedom of movement in the optical head 102 with controlled friction the massage ball 108 is transparent at the wavelength of the therapeutic light 110 that is produced by the light source 104 thus the therapeutic light 110 can transmit through the massage ball 108 to the subject biological tissue 128 to be treated it is also possible to incorporate a group of optical elements between the light source 104 and the massage ball 108 for controlling the divergence angle intensity distribution uniformity beam size etc of the therapeutic light 110 the light source 104 is preferably a high power semiconductor laser or led such as a class iv semiconductor laser.
