Fourier Domain Mode Locking Laser Sweeping Based On Optical Parametric Amplification

Abstract

We present a Fourier domain mode locked (FDML) laser scanning from 1516 to 1550 nm and 1567 to 1597 nm using optical parametric amplifier (OPA) as the gain medium. The output power of-4.85 dBm with sweep rate of 39.6 kHz is achieved.

Wavelength-swept spectral and pulse shaping utilizing hybrid Fourier domain modelocking by fiber optical parametric and erbium-doped fiber amplifiers

“…Spectra generated using the individual one-pump OPA and the C-band EDFA are illustrated in Fig. 3(a) [20] and Fig. 3(b), respectively.…”

“…The amplified spontaneous emission (ASE) background is ~40dB lower than peak power of the hybrid FDML output. Figure 5(a) shows the pulse waveform of the one-pump OPA FDML [20], it can be observed clearly that in both the forward and backward sweep, there is quite a large notch in the middle of each pulse. From Fig.…”

“…The schematic diagrams of EDFA FDML [16] and OPA FDML [20] (also the hybrid FDML) are shown in Fig. 1 In Fig.…”
