Classical phase space dynamics is governed by a continuity equation. The same is true for quantum dynamics in phase space: Wigner's quantum phase space current, J, governs the evolution of Wigner's phase space distribution W. Unlike the classical case, W is typically negative in some regions.

 

We report our implementation of a squeezer, by generating squeezed vacuum state at 1064 nm through a bow-tie OPO cavity operated below threshold. With the help of our home-made BHD, characterized with a CMRR more than 80 dB, we measured noise reduction up to 10 dB in the squeezed quadrature.

 

We report the first multi-line optical parameter oscillator (OPO) whose spectrum can be electro-optically switched using an aperiodically poled lithium niobate (APPLN) working as a nonlinear medium and a tunable spectral filter. The OPO can oscillate at 1540-nm, 1550-nm, and both wavelengths simply by switching the voltage on the APPLN.

 

We have demonstrated a nJ-level continuum generation ranging from 540-1210 nm based on phase-matching dispersive wave generation with the use of photonic crystal fibers and a Cr:forsterite laser. We expect to characterize the generated 5-fs pulses from the output and even shorter 3-fs pulses achievable with proper dispersion compensation.

 

We developed a high-power fiber-format multi-wavelength femtosecond laser source based on Yb: fiber laser and a photonic crystal fiber for wavelength conversion ranging from 800nm to 1400nm. Fluorophore-stained or transgenic bio-samples were further imaged, demonstrating the capability of simultaneous multi-color excitation.

 

We demonstrate experimentally a 10 GHz erbium-doped mode-locked fiber laser with good optical frequency stability. A high finesse Fabry-Pérot etalon as an intra-cavity optical comb filter is utilized for stabilizing the laser operation. With the proper control of the cavity length, the supermode noises can be suppressed successfully.
