Cr⁴⁺:YAG Crystal is a crystal with excellent performance as a passive Q - switch for Nd:YAG, Nd:YLF, Nd:YVO₄, and other neodymium - doped or ytterbium - doped lasers with wavelengths from 0.8 to 1.2μm. With a passive Q - switch or saturable absorber, sufficient laser pulses can be obtained without the need for an electro - optical switch. Due to its good chemical stability, durability, UV resistance, good thermal conductivity, high damage threshold (>500MW/cm²), and ease of handling, it will replace the commonly used LiF and dyes in the field of passive Q - switches and become an excellent choice for 1μm Nd - doped lasers.
