…cooling water circulates
around a closed path that includes the laser and a heat
exchanger. The heat generated by the laser is removed in the
heat exchanger, which must itself be cooled by either liquid or
air.

…(diffusion cooling).
Thus, the conventional gas circulation
systems involving roots blowers or turbines
are not required. The crucial advantage of
this laser principle is that the laser gas neither
needs to be circulated nor to be renewed
permanently. That means that…

…medium has stored energy. In simple terms, the excited state of the
gain medium has a much longer lifetime than the trip time for photons to circulate around the
CW cavity. Specifically, the excited state lifetime in Nd-based DPSS lasers is microseconds,
whereas the cavity trip time…

Internal Cooling
In some of Coherent's (Optoskand) fibers (QBH, QD), the volume behind the quartz block is filled
with circulating cooling water. This means that the radiation removed from the cladding by the
mode stripper is directly absorbed in water, rather than being…

…in configuration to allow for different-sized stacks
(see Fig. 3).
For high LD powers and water-flow
rates, a closed-loop water circulation system conserves water and thus costs. Such
systems are often cooled by laser chillers,
which can operate via either TEC or via

…4%.
In excimer lasers the excess discharge energy has to be
removed efficiently as excess heat. An internal fan causes a
forced circulation of the laser gas in order to keep the active
medium renewed in the lasing region and to obtain a high
flow rate through the gas filter…
