The bulk optical cooling of solid state materials by placing the cooling medium inside a laser cavity was studied. Yb3+: KY(WO 4)2 (KYW) laser and an uncoated sample of 2%-doped Tb 3+:ZrF4-BaF2-LaF3-AlF 3 -NaF (ZBLAN) glass were used as laser system and cooling medium, respectively. The advantage of this method is that no reflective coatings are required along the axis of propagation of the radiation because the cooling medium may be cut with Brewster-angled end faces having zero reflection losses. The intracavity absorption in this method provides a means to evaluate the bulk cooling performance of the cooling material.
