Are all diode lasers comparable regarding wave legnth and fluence?

February the 8:th I’m going to have full body LHR treatment with a MedioStar diode laser and I wonder if the wave length all diode lasers (such as the Ligth sheer) are the same and if the fluences is comparable. Is 30J with Light sheer and MedioStar the same? Because I have heard that with the Light sheer you need to get treated with 30J or more to have good results.
