Dual Amplification 850 nm FDML Laser

Fourier domain mode locked (FDML) lasers have been widely used in optical coherence tomography (OCT) for many years at 1550 nm, 1310 nm and 1064 nm [1]–[4]. Developing a shorter wavelength FDML laser is interesting for eye imaging for instance, due to less water absorption and increased scattering which can improve the contrast of low scattering features.
