OEM/ODM China Clear Quartz Substrates - Lamp Flow Tube For Laser Pumping Cavity – LZY

Lamp Flow Tube For Laser Pumping Cavity
The samarium doped glass can block all UV light below 400nm, it is very good UV filter. Samarium doped glass can fluoresce in the visible range, which causes some increase in pumping efficiency with lasing mediums. It also can block the 1064nm wavelength.
By CNC machining, we can create different shapes and dimensions of laser flow tubes.

Flowtubes and Filter Flowtubes combine and integrate in one solid optical element attributes and technical characteristics necessary to perform simultaneously the following functions:
● cooling duct for both lamp(s) and laser rod(s);
● Filtering-absorbing undesired UV radiation, thus protecting the rod from long term solarizat
● Attenuating “lateral depumping” effects i.e. energy losses caused by the rod’s side emission, by absorbing it and preventing its backreflection.

Flowtubes satisfy only the first of the above functions while Filter Flowtubes may satisfy the first two or all three of them. This last category is of increasing interest for Nd:YAG Q-Switched lasers. For this case, Samarium doped Glass is the material of choice because it attenuates lateral depumping effects, thus avoiding super luminescence phenomena and absorbing undesired UV radiation.
