Brillouin Fiber Laser using Nonlinear Birefringent Photonic Crystal Fiber

A Brillouin fiber laser using a highly nonlinear birefringent photonic crystal fiber is reported. The core of the fiber was elliptical in shape. A single-longitudinal-mode high power fiber laser was used as a Brillouin pump and the laser produced multiwavelength output with a 0.04 nm separation. Adjusting the polarization controller plates made it possible to obtain a single wavelength laser. T...

Laser-cooled atoms inside a hollow-core photonic-crystal fiber

We describe the loading of laser-cooled rubidium atoms into a single-mode hollow-core photonic-crystal fiber. Inside the fiber, the atoms are confined by a far-detuned optical trap and probed by a weak resonant beam. We describe different loading methods and compare their trade-offs in terms of implementation complexity and atom-loading efficiency. The most efficient procedure results in loadin...

Mode-Selective Fiber Laser Using a Photonic Lantern

We experimentally demonstrate a transverse mode-selective fiber laser using a photonic lantern. The output modes of laser are switchable among the 6 LP modes supported by the gain fiber. Their slope efficiency, optical spectra, and mode profiles are measured. Introduction Large mode-area optical fiber can support highorder of linear polarization (LP) modes. There are many motivations for produc...

Two-photon laser scanning fluorescence microscopy using photonic crystal fiber.

We report the application of a simple yet powerful modular pulse compression system based on photonic crystal fibers that improves on incumbent two-photon laser scanning fluorescence microscopy techniques. This system provides more than a sevenfold increase in fluorescence yield when compared with a commercial two-photon microscopy system. From this, we infer pulses of IR radiation of less than...
