Is laser hair removal hygienic? Could someone contract STDs?

I am under going laser hair removal at a Laser Center. I've only had one treatment, but after the first treatment I realized I forgot to ask about how the device is cleaned between patients. Is there any chance of STD transmission with the hand piece? How likely would it be for a herp germ to get in the crevice and transmit to a patient? How should I approach this conversation with my Laser Hair removal specialist? What type of cleaner is used for the device and will this cleaner kill STD viruses?
