We demonstrate a coherent picosecond pulsed fiber laser for the high frame-rate optical time-stretched microscopy at 1.0 µm. Real-time flow imaging with a frame rate of 26.25 MHz is achieved based on this source.
A Fourier domain mode locking laser with dispersion management at long-wavelength band is investigated. Sweeping bandwidth and obtained OCT axial resolution compared with the case without dispersion control is enhanced by 33% and 30%, respectively.
We present a Fourier domain mode locked (FDML) laser scanning from 1540 to 1570 using two-pump optical parametric amplifier (OPA) as the gain medium. The sweep rate of 39.683 kHz is achieved.
We demonstrate photonic generation of square waveform using fiber optical parametric oscillator without the external signal source. Stable square waveform pulse train at the repetition rate of 1.133 GHz is achieved.
We demonstrated a mode-locked Nd:GdVO4 laser of operating at 912 nm. Using a semiconductor saturable-absorber mirror for passive mode locking, stable output power of 22.6 mW is obtained at a repetition rate of 176 MHz.
