ANSWER: Both a and b
Scientists have used lasers to refrigerate bayer and other liquids under real life conditions. Infrared laser has been used to cool water by 2 degree C and could help industrial users "point cool" tiny areas with a focused point of light. Microprocessors can even be used for cooling specific components in computer chips to prevent overheating.
