Solid state laser pumped Raman laser apparatus - has linking mirrors formed from single transparent material guiding pump light to Raman cell, dichroic beam splitter and triple mirror being in Raman beam path

摘要

The laser apparatus includes a pump laser medium (1), e.g. a flash light pumped Nd:YAG, a Raman cell (2), and two linking mirrors (5,62). The linking mirror guides pump laser light from the pump medium to the Raman cell, e.g. of methane. Provided with the linking mirrors, including a dichroic beam splitting mirror (62), is a triple mirror (7). The beam splitter filters out the Raman radiation from the pump light and the triple mirror is in the beam path of the Raman radiation. All three mirrors are compacted to form a single body of transparent material, the linking mirrors being formed from a reflection prism (50) with a normal prism (8) and the triple mirror connected to the dichroic beam splitting mirror.
