Nd:YAG Crystal
Nd:YAG is an earlier and well-known laser host crystal. Since it combines obvious advantages in basic properties of laser crystal, Nd:YAG has ubiquitous presence in near-infrared solid-state lasers and their frequency-doubler, tripler, and higher order multiplier. Other HR coatings, e.g. HR@1064nm & 532nm, 946nm, 1319nm etc. are also available THATSHIGH Quality Standard of Nd:YAG Crystal Diameter (mm) | Standard Grad | Excellence Grade | Super Excellence Grade φ3~6.35 | ≤ 0.5 fringes/ inch | ≤ 0.25 fringes/ inch | ≤ 0.1 fringes/ inch ≥ 25 dB | ≥ 28 dB | ≥ 30 dB φ7~10 | ≤ 0.7 fringes/ inch | ≤ 0.4 fringes/ inch | ≤ 0.16 fringes/ inch ≥ 22 dB | ≥ 25 dB | ≥ 28 dB φ11~13 | ≤ 1 fringes/ inch | ≤ 0.6 fringes/ inch | ≤ 0.2 fringes/ inch ≥ 20 dB | ≥ 23 dB | ≥ 26 dB φ14~16 | ≤ 1.2 fringes/inch | ≤ 0.8 fringes/inch | ≤ 0.25 fringes/inch ≥ 18 dB | ≥ 20 dB | ≥ 23 dB Note: Nd:YAG rods for 946 nm or 1319 nm lasers, and higher grade or specific Nd:YAG rods or slabs can be provided.

Neodymium-doped yttrium vanadate (Nd:YVO4). Nd:YVO4 is an excellent crystal for diode-pumped lasers, especially low-to-medium power. Compared with Nd:YAG, Nd:YVO4 offers higher pump absorption and a larger stimulated-emission cross-section. Diode-pumped Nd:YVO4 combined with LBO, BBO, or KTP provides efficient frequency doubling for NIR, green, blue, and UV all-solid-state sources. Nd:YVO4 lasers serve machinery, materials processing, spectroscopy, wafer inspection, displays, medical testing, laser printing, and storage. Nd:YVO4 diode-pumped systems are replacing water-cooled ion and lamp-pumped lasers, especially for compactness and single-longitudinal-mode output.
