Yb:CALGO Laser Crystal (Yb:CaGdAlO₄) – Ultrafast Femtosecond Laser Gain Medium

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
