Abstract
A laser device is provided that includes an element made of laser-active material and a cladding element bonded to the element so as to allow heat exchange by heat conduction between the cladding element and the element. The laser-active material emitting laser light when excited by pump light. The element being made of a glass. The cladding element being made of a material that exhibits an absorption coefficient for the pump light that is lower than a corresponding absorption coefficient of the glass. The element and cladding element being configured so that the pump light can be directed through the cladding element into the element and/or so that the pump light can be directed through the element into the cladding element.
Claims18
A laser device comprising:
- an element made of laser-active material that emits laser light when excited by pump light, wherein the element is made of a glass;
- and
- a cladding element bonded to the element so as to allow heat exchange by heat conduction between the cladding element and the element, wherein the cladding element is made of a material that comprises phosphate crown glass or phosphate dense crown glass and exhibits an absorption coefficient for the pump light that is lower than a corresponding absorption coefficient of the element, and
- wherein the element and cladding element are configured so that the pump light is directed through the cladding element into the element and/or so that the pump light is directed through the element into the cladding element.
A laser device comprising:
- an element made of laser-active material that emits laser light when excited by pump light, wherein the element is made of a glass;
- and
- a cladding element bonded to the element by anodic bonding so as to allow heat exchange by heat conduction between the cladding element and the element, the cladding element being made of a material that comprises fluorine ions or comprises a fluorine phosphate glass and exhibits an absorption coefficient for the pump light that is lower than a corresponding absorption coefficient of the element, and
- wherein the element and cladding element are configured so that the pump light is directed through the cladding element into the element and/or so that the pump light is directed through the element into the cladding element.
