The subject matter described herein includes a method of generating a collimated electromagnetic emission. The method includes producing an excitation in a sample of multiple particles by vibrationally stimulating the sample thereby transitioning each particle of at least a quantity of the multiple particles from a lower first energy state to a higher second energy state. The method also includes generating a collimated electromagnetic emission by de-excitation of at least a portion of the quantity of the multiple particles. A related apparatus is also provided.
