We demonstrate a highly sensitive acoustic vibration sensor based on a tapered-tip optical fiber acting as a microcantilever. The tapered-tip fiber has a unique output profile that exhibits a circular fringe pattern, whose distribution is highly sens

This paper presents short wavelength operation of tunable thulium-doped mode-locked lasers with sweep ranges of 1702 to 1764 nm and 1788 to 1831 nm. This operation is realized by a combination of the partial amplified spontaneous emission suppression

Harmonic focal point axial modulation (h-FPAM) in nonlinear optical microscopy is introduced and used to enhance the axial resolution and the signal to background ratio by modulating the focal point of a beam of femtosecond pulses train along the axi

Among the most important challenges of microscopy—even more important than the resolution enhancement, especially in biological and neuroscience applications—is noninvasive and label-free imaging deeper into live scattering samples. However, the

In this paper, the effect of stimulated Brillouin scattering (SBS) on increase in the output power of a fiber laser is investigated by solving the steady-state rate equations with the SBS. The effects of fiber core diameter, cavity length, reflectivi
