Where to Buy Laser Gain Media

Thanks to their high rare-earth solubility (up to 100,000 ppm) and low phonon energy, LVF fluoride fibers offer dozens of active transitions, enabling a broad range of applications from visible to the mid-infrared. LVF offers the largest range of rare-earth doped fibers in the world.

LVF active fibers are available as RE doped single-mode fibers and rare-earth-doped double cladding fibers.

MegaWatt Lasers Inc. has a large inventory of Nd:YAG, Er:YAG and CTH:YAG laser rods. We also can assist in the design and modeling for various applications.

Shalom EO offers a variety of rare-earth-doped laser crystals, including crystals made of

• Nd:YAG
• Nd:Ce:YAG
• Nd:YVO₄
• CTH:YAG crystals
• Er:YAG crystals
• Yb:YAG crystals
• Ti:sapphire crystals

and also diffusion-bonded crystals. Nd:YAG crystals and Nd:YVO₄ crystals are ideal for 1064-nm lasers, while Nd:Ce:YAG, CTH:YAG and Er:YAG crystals are excellent for medical and cosmetic laser applications. Ti:sapphire crystals are ideal for ultrafast laser systems, and diffusion-bonded crystals are suitable for OEM compact laser systems.

Laserton offers various types of laser crystals based on materials like Nd:YAG, Nd:YVO₄, Yb:YAG and Cr⁴:YAG.

Also, Laserton offers gain chips based on Er:Yb:glass, which is bonded to a Co:Mg:Al₂O₄ saturable absorber crystal for passive Q switching. These can be used to produce eye-safe lasers emitting at 1535 nm, pumped with a laser diode at 940 nm.

Exail (formerly iXblue) offers a wide range of specialty optical fibers for lasers and amplifiers. We master erbium, erbium/ytterbium, ytterbium, thulium, holmium, thulium/holmium, neodymium, dysprosium, and phosphorous gain media. PM version are available, and Large Mode Area (LMA) or Very Large Mode Area (VLMA) versions as well. Depending of the requirement, single clad fibers are available for core pumping, double clad fibers for clad pumping. Triple clad and all glass structures are also available.

Crystalline laser gain media are know as most reliable and efficient. GWU offers all common laser crystals (Nd:YVO₄, Nd:YAG, Yb:YAG etc.) with a broad variety of specifications. Besides the well-established materials, innovative crystals with outstanding properties like Yb:CALGO can open new horizons for demanding laser applications.
