Burn after Candela Alexandrite Lazer treatment. What are my treatment options? (photos)

I made Candela Alexandrite Lazer treatment 5 days ago and I have terrible burn. My doctor said that she made the treatment on 14 charge. She was also confused why did I get such kind of burn. It wasn't first time I made Candela Laser treatment. I have dark color of skin but I didn't have sunburn on suntan. What treatment would you advise ?
