Claim Text:
1. A microchip laser, comprising: a microchip laser base comprising a gain region coupled directly to a passive Q-switch region such that an emitting surface of the gain region is in direct contact with a receiving surface of the passive Q-switch region; a solid etalon coupled to the microchip laser base; and an interfacial coating disposed between the microchip laser base and the solid etalon such that a first surface of the interfacial coating is in direct contact with an emitting surface of the passive Q-switch region and a second surface of the interfacial coating is in direct contact with a receiving surface of the solid etalon, the interfacial coating having a reflectance that substantially matches a Fresnel reflectance of an emitting outer surface of the solid etalon; wherein:
