Yb:KGW (Yb³⁺:KGd(WO₄)₂) is a high-performance ytterbium-doped laser crystal widely used in ultrafast, high-power, and high-efficiency solid-state laser systems. It offers a broad e mission bandwidth, high absorption cross-section, and excellent thermal properties, making it an ideal gain medium for femtosecond and picosecond lasers. Compared with Yb:YAG, Yb:KGW provides broader gain bandwidth, enabling shorter pulse generation and superior wavelength tunability. Its strong absorption near ~980 nm diode pumping allows efficient direct diode pumping with reduced thermal load. Yb:KGW crystals are extensively used in ultrafast oscillators, regenerative amplifiers, chirped-pulse amplification (CPA) systems, and advanced scientific laser platforms. Precision crystal growth and optical-grade polishing ensure low scattering loss and stable laser performance. We supply high-quality Yb:KGW single crystals with controlled doping concentration, crystallographic orientation, and optional AR coatings to support both research laboratories and OEM laser manufacturers. Key Features Broad emission bandwidth for ultrafast lasers High absorption cross-section at ~980 nm Suitable for femtosecond and picosecond pulse generation Efficient diode pumping with low thermal load Excellent optical and thermal stability Available in multiple cuts and custom dimensions Typical Applications Femtosecond and picosecond laser oscillators Regenerative and multi-pass amplifiers Chirped-pulse amplification (CPA) systems Ultrafast spectroscopy Nonlinear frequency conversion systems Scientific and industrial ultrafast lasers Frequently Asked Questions — Yb:KGW Laser Crystals What is a Yb:KGW crystal? + Yb:KGW (Ytterbium-doped Potassium Gadolinium Tungstate) is a diode-pumped laser crystal known for its broad emission bandwidth, high gain, and excellent performance in ultrafast and femtosecond laser systems.
