Second harmonic of Er-doped iber laser operates at wavelength of 780 nm and in a number of applications can replace the powerful yet less reliable solid-state Ti:S lasers. Easy to use design, turn-key operation, small footprint greatly facilitate any research in which the laser is involved. Lack of laser experience is not a problem with the fiber lasers, only general electronics and light physics knowledge is required to work with the unit. EFOA-SH is also a perfect source for ampliier system seeding due to one-box compact design and lack of expensive pump laser as in case of Ti:S solid-state seed.
