Lasers are used everywhere from CD players, industrial cutting to laser eye surgery. But before the laser, there was the maser and it produces microwaves instead of light in a laser. However, due to its extreme cooling requirement maser never became as widespread as the laser. In this lecture, we will explore briefly the history of laser and maser followed by the recent developments in solid-state laser technology (in Alexandrite), and the newly invented room-temperature maser (in Diamond).
