apogee alexandrite

Hi,
I have had my first 4 treatments using cynergy yag (cynosure) and just started my 5th series of body treatment. The doctor decided to use the apogee alexandrite for my arms since the hairs have become finer and thought this would be more effective than continuing on the yag for my skin type IV.
The setting for the apogee alexandrite was 30j/15mm/40ms for full arms. I need some advice on the settings, spots size and pulse width for apogee alexandrite. I tried to search other post to get this info but wasn’t successful. I am schedule to have my back treated in a few days and wanted to make sure to get the right settings in case the above setting for the arms were too low or ineffective. Thank you so much.

these settings are ok. If the hair is fine, they should decrease the pulse. I think the lowest is 5ms, so the closer to that, the more effective on fine hair without decreasing the joules or spot size if possible.
