Welcome to the forums.
That is what we know in the Mac world as a Kernel Panic.
It can be caused by a multitude of things. ie: 3rd Party Apps or a usb peripheral
Best bet is too Repair Permissions via Disk Utility in Applications>Utilities
Open DU click on the HD in the left column. Make sure First Aid is clicked then down the bottom Repair Permissions.
Once its finished (this could take a while and take no notice of the logs) reboot the Mac. Hope that does it, but if not fault find by disconnecting your USB peripherals 1 by one until it doesn't happen. OR look for and Apps you recently installed or Extensions.
