Abstract
Fluctuations in optical output are positively suppressed in a laser apparatus that adjusts the temperature of a housing that contains constituent components of a laser to be a predetermined temperature. Constituent components of a laser that include a resonator constituted by the back end surface of a laser diode and a resonator mirror are contained within a housing. The housing is bonded to a Peltier element via an adhesive layer. The Peltier element is driven based on detected temperatures within the housing to adjust the housing to be of a predetermined temperature. An adhesive layer in which a plurality of substantially uniformly shaped spacers that regulate the distance between the housing and the Peltier element are dispersed is employed as the adhesive layer.
Claims9
A laser apparatus comprising:
- a housing, within which constituent components of a laser that include a resonator and a laser diode which emits laser light toward the resonator are contained;
- a temperature adjusting element which is bonded to the housing via an adhesive layer;
- and
- the temperature adjusting element being driven based on a detected temperature of the housing to adjust the temperature of the housing to be a predetermined temperature;
- wherein the adhesive layer being that in which a plurality of substantially uniformly shaped spacers that regulate a distance between the housing and the temperature adjusting element are dispersed, the spacers being constituted by one of a glass and a ceramic.
