Yb:CALGO Laser Crystal (Yb:CaGdAlO₄) – Ultrafast Femtosecond Laser Gain Medium Yb:CALGO (Ytterbium-doped Calcium Gadolinium Aluminate, Yb:CaGdAlO₄) is a high-performance laser crystal widely used in diode-pumped ultrafast and femtosecond laser systems. Owing to its exceptionally broad emission bandwidth, high efficiency, and favorable thermal properties, Yb:CALGO has become one of the most attractive gain media for generating ultrashort pulses in the 1030–1050 nm wavelength range. Key Features Broad emission bandwidth suitable for femtosecond pulse generation High absorption around 976–980 nm for efficient diode pumping Emission wavelength around 1030–1050 nm Excellent gain medium for mode-locked oscillators and regenerative amplifiers Suitable for high-average-power and high-repetition-rate lasers Good thermal conductivity and reduced thermal lensing Ideal for frequency combs, dual-comb spectroscopy, nonlinear optics, and scientific research applications Typical Applications Femtosecond oscillators Ultrafast amplifiers Frequency comb generation Dual-comb spectroscopy Nonlinear frequency conversion Scientific and industrial laser R&D Available Specifications Doping concentration: 1–5 at.% Yb (custom available) Custom dimensions available upon request Laser-grade optical polish AR coating available for: Pump wavelength: 976–980 nm Laser wavelength: 1020–1080 nm Orientation and mounting options available Quality High optical quality Laser-grade polishing Carefully inspected before shipment Suitable for research laboratories, universities, and laser development projects Custom sizes, coatings, and doping levels are welcome.
