Ytterbium Doped Laser Glass

Nd doped glasses	Erbium laser glasses	Ytterbium doped glasses	Faraday rotator glasses

Yb³⁺-doped glass materials are desirable for generation of ultra short pulses and as tunable laser sources because of their broad absorption and emission bandwidths

Yb³⁺ doped phosphate glass (YP1):
Long lifetime
Very low temperature coefficient of optical
path length of +0.42x10-6/^oC
Fluorescence lifetime >2 ms

Yb³⁺ doped borete glass(YB1):
Low thermal expansion coefficient
Negative temperature coefficient of
refractive index
High Cross section for stimulated
emission of 1.65 X 10 -20 cm²
