Activated phosphate laser glasses
Chromium-Ytterbium-Erbium activated glasses are designed for maximal efficiency (up to 2.5 - 3.0 % in free running) under Xe flash lamp pumping in the regime of rare pulses.
   Neodymium-Ytterbium-Erbium activated laser glasses are designed for efficient (up to 2.0 - 2.5 %) flashlamp pumped operation in case of repetitive pulses. Heat dissipation in them is lower than that in Chromium-containing glasses and they exhibit no temperature decrease of lasing parameters.
   Concentrated Ytterbium-Erbium phosphate laser glasses are for laser diode pumped operation. Lasing wavelengths - 1.05 and 1.35 µm. These glasses have extremely high (4 x 1021 cm-3) Ytterbium ions content, resulting in high absorption coefficient of InGaAs Laser diode radiation (up to 35 cm-1 at the peak at 975 nm). Erbium content can be varied depending on the customers demands (typically (3 - 5) x 1019 cm-3 for side pumping and (1.5 - 2) x 1020 cm-3 for microchip lasers). Availability: rods or plates according to customer's demands with appropriate antireflective or reflective coatings.
