Abstract

We report on a single-pass device that efficiently converts the broadband near-infrared output from a femtosecond fiber laser into a narrow spectrum in the visible. With fan-out poled MgO:LiNbO3 we obtain subpicosecond, continuously tunable pulses in the 520700nm range. Conversion efficiencies as high as 30% are observed at typical pump power levels of 30mW, corresponding to average output powers up to 9.5mW. The specifications of our device are ideal for applications in confocal microscopy and frequency metrology.

Fig. 1
Fig. 1

Scaling of the normalized efficiency of the sum-frequency process f 1 + f 2 = 2 f (where f 1 = f + f 0 and f 2 = f f 0 ) as a function of frequency spacing f 0 . Parametric curves are shown for fundamental wavelengths 1.0 and 1.4 μ m for 1 mm and 2 mm long crystals. The corresponding grating period Λ assumes the value that phase matches the degenerate case of second-harmonic interaction [ f = 0 , with n ( f = 0 ) = 1 ].

Selection of recorded visible spectra within the tuning range of our device for crystal length L and grating period Λ: (a) L = 1 mm , Λ = 6.45 7.8 μ m ; (b) L = 1 mm , Λ = 9.73 15.41 μ m ; (c) L = 2 mm , Λ = 7.25 11.72 μ m . The spectral power is shown in absolute values, and typical average power levels (achieved without readjustment) are also noted.

Pulse-duration measurements of the visible pulses as a function of wavelength for two crystal lengths. Assuming Gaussian pulses, we have derived durations from autocorrelation traces.
