A laser beam delivery system transmits a laser beam with sufficient power to heat treat a work surface. The laser beam is reflected and focused by a first reflector to a second reflector and then onto the work surface. The second reflector is mounted angularly to a rotatable shaft such that when the shaft is rotated, the second reflector rotates about a first optical axis which is separate from a second axis or shaft and at a frequency that produces an integrated energy ring that remains coupled.
