Description

A microlaser is provided that has a microresonator and a pump source for side pumping the microresonator. The microresonator includes an active gain medium and a Q-switch that extend lengthwise between the opposed end faces of the microresonator. The pump source is therefore positioned so as to introduce pump signals into the microresonator via the side surface that is adjacent to and defined by the active gain medium. By side pumping the microresonator, the microlaser can generate a series of pulses having greater pulse energies and greater average power levels than the pulses provided by conventional microlasers. In addition, the side pumped microlaser can also generate pulses having greater pulse widths than the pulses provided by conventional microlasers of a similar size. As such, the side pumped microlaser can be employed in more demanding applications that require pulses having greater pulse widths as well as pulses that have greater pulse energy and greater average power than are typically provided by conventional end pumped microlasers.
