Method of producing a therapeutic laser device (TLD). The TLD includes stretchable, flexible membranes which comprise a high pressure air cavity. High air pressure is produced by fans which are speed controllable by computer. Standoff posts provide, an attachment function, and a separation function between the TLD and the patient. Semiconductor laser diodes and lens sets in a two dimensional array produce the therapeutic laser light. Cooling air tubes direct air controlled by temperature sensors from the high pressure cavity onto laser diodes. Capacitive proximity sensors in conjunction with infrared radiation sensors confirm close contact with a patient and allow lasing. Power is supplied either by battery or by connection to mains power. A touch screen computerized device with wireless communication displays information to the user and controls the therapy session. The TLD and the power supply both have stretchable straps enabling the TLD to be fixed to the patient.
