YB:YAG (Ytterbium-Doped Yttrium Aluminum Garnet Crystal)
Yb:YAG is a promising solid-state laser medium particularly suited to diode pumping compared with traditional Nd-doped systems. Its broader absorption bandwidth than Nd:YAG reduces diode-laser temperature-management requirements. Upper-state lifetime is longer, and thermal load per unit pump power is stated as 3–4 times lower. Yb:YAG at 1030nm can replace Nd:YAG at 1064nm, while its 515nm second harmonic can replace 514nm argon-ion lasers.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
