Abstract
The electro-optic apparatus includes a primary heat sink and at least one submount mounted to the heat sink. The electro-optic apparatus also includes a pump source, such as a laser diode, mounted to a sidewall of the at least one submount. A secondary heat sink is also mounted to the at least one submount with an active gain medium mounted, in turn, to the secondary heat sink. Typically, the active gain medium is part of a microlaser that also includes a passive Q-switch. The active gain medium is mounted to the secondary heat sink such that the active gain medium extends in a cantilevered fashion from the secondary heat so as to overlie the pump source such that the output of the pump source pumps the active gain medium. By adjusting the position of the secondary heat sink to the at least one submount, the spacing between the pump source and the active gain medium can be precisely controlled, thereby also controlling the characteristics, such as the frequency, of the output signals emitted by the electro-optic apparatus. Advantageously, the at least one submount includes first and second submounts, both of which are mounted to the primary heat sink in a spaced apart relationship.…
