Abstract
A laser diode is provided with a casing that encloses a light-emitting crystal. The casing includes a transparent member through which the light passes. A portion of the diode is positioned within a holder and means is provided for cooling the diode. To reduce condensation of moisture which is present within the holder, upon the transparent member, a sleeve formed of a thermally high conductor material such as copper is placed about the casing with close physical contact therebetween.
