1. An impingement cooling apparatus comprising:
a housing having a window to be directed at a treatment area and further having a plenum fluidly coupled to the window;
an optically transparent region on the window of the housing through which electromagnetic radiation (EMR) from a source can exit through the optically transparent region of the window and be directed at the treatment area; and
at least one opening on the window of the housing through which a fluid flow exit the housing to be directed to the treatment area to maintain the treatment area at a therapeutically acceptable temperature range while avoiding interference with the EMR being directed at the treatment area, each of the EMR and the fluid flow traveling along at least a portion of the plenum before exiting through the window.
