Ceramics laser beam visualizers
PhotonTechSystem LLC offers ceramic visualizers for medium and high power infrared laser radiation. These visualizers can be used to detect and localize IR radiation, as well as to visually assess the spatial distribution of laser radiation. A wide spectral range ensures their use when working with various commercial IR lasers: neodymium (YAG:Nd, YLF:Nd, YVO4:Nd, etc., 1.03-1.06 μm), yttrium (CaF2:Yb, YAG:Yb, fiber, etc., 0.98-1.1 μm), erbium (Er, 1.53-1.6 μm), diode lasers (808 nm, 940 nm, 980 nm, 1450, 1550 nm, etc.).
Visualizers IR3, IRV-R, IRV-G, IRV-RG are made of ceramics doped with rare-earth ions. Ceramic visualizers IR3, IRV-R, IRV-G, IRV-RG allow obtaining a stable image of a laser beam in time under normal illumination conditions without using preliminary "charging" with other radiation sources. Their operation is based on the phenomenon of anti-Stokes luminescence. Ceramic visualizers, in comparison with visualizers in the form of cards of the IR1, IR2, IR4 series, have a higher destruction threshold, which determines their use when working with powerful continuous and pulsed lasers.
The operation of the IRV-Q visualizer is based on the phenomenon of the second harmonic. This model is used to work only with pulsed lasers in the spectral range of 0.85 - 1.4 µm.
IR3 visualizers have higher spectral sensitivity compared to IRV-R, IRV-G, IRV-RG, IRV-Q visualizers and can be used with low-power lasers. However, IR3 visualizers have a lower destruction threshold compared to other ceramic visualizers.
IRV-RG visualizers have a wide spectral range of operation (0.75 - 1.09 µm and 1.47 - 1.6 µm) and higher spectral sensitivity compared to IRV-R, IRV-G, IRV-Q models.
IRV-R visualizers, like the IRV-RG model, have a wide spectral range of operation, but are significantly inferior to it in spectral sensitivity.
The IRV-G model is designed to work with lasers in the range of 0.85 - 1.09 µm.
All models of ceramic visualizers consist of a ceramic disk fixed in a metal frame. The visualizer is positioned using a long handle.
The materials used in the manufacture of visualizers do not contain radioactive substances, are non-toxic and can be used when working with laser radiation with a high power density
When working with laser radiation sources, it is necessary to comply with the requirements of laser safety technology.
