AVESTA's ultrafast laser technology is derived from the Quantum Radio Physics Department of the P.N. Lebedev Institute of Physics in Russia. The company was founded in 1990 by two Nobel laureates, Basov and Prokhorov, and is headquartered in the academic town of Troitsk in southwestern Russia.
The company is committed to the development of ultrafast laser technology and provides professional products for global scientific research and industrial customers. Our products include femtosecond fiber lasers, titanium sapphire femtosecond lasers, amplifiers, autocorrelation devices, third-order cross-correlation devices, pulse selectors, and more.

Product Overview:
The second harmonic working wavelength of erbium-doped fiber lasers is 780nm, which can replace powerful but less reliable all solid state Ti: S lasers in many applications. Due to its simple use, simple operation, and compact structure, this type of laser will greatly promote research in the field of lasers.
EFOA-SH adopts a single box design, compact structure, and low price, making it a very good seed source laser for laser amplification systems. A perfectly designed laser amplifier system. However, solid-state Ti: S lasers are expensive.
