We demonstrate a high quality optical cavity with a 30 micron mirror on a micromechanical resonator. An optical finesse of 2100 is measured via cavity ring-down. High mechanical quality of the resonator is also observed.
We have shown experimentally and theoretically that the phase control of all independent stimulated Brillouin scattering-phase conjugate mirrors (SBS-PCMs) can be achieved by self-generated density modulation without coupling the beams.
By high-finesse cavity enhancement, we achieve 101plusmn9 MW/cm2 cw intracavity intensity on the surfaces of the cavity mirrors. No permanent damage to the mirrorspsila coating is found and distortion measurement of mirrorspsila surfaces is performed.
Towards overcoming the size limitations of conventional two-photon fluorescence microscopy, we introduce laser-scanning instrumentation based on a microelectromechanical systems (MEMS) scanner and describe two-photon microscopy and microendoscopy with fast-axis acquisition rates up to 3.5 kHz.
A flexible saturable-absorber mirror was piezoelectrically vibrated for Q-switching of a laser-diode-pumped Nd3+:YVO4 microchip laser. The double Q-switch led to increase of the peak pulse-power and of the repetitive-pulse stability in power and rate.
We describe the fabrication of a novel type of saturable absorber mirrors based on polymer embedded carbon nanotubes and we demonstrate their performance in mode-locking an Er/Yb:glass laser: 68 fs (45fs Fourier limit) at 85 MHz repetition-rate.
We report the generation of a 10 GHz 2.5 ps pedestal-free optical pulse from a seeded gain-switched DFB laser diode and a compressing nonlinear amplifying loop mirror suitable for multiplexing into a 100 Gb/s transmission system.
We report the achievement of a square flattop mode in a diode pumped 100 mJ regenerative amplifier. This mode is selected by 2 diffractive mirrors which provide a high modal discrimination and low roundtrip loss.
We demonstrate the monolithic integration of a VCSEL half-cavity and a single-layer sub-wavelength grating as its top mirror. Polarization-selective amplified stimulated emission with selection ratio of 20 dB was obtained.
A pair of nearly identical volumetric Bragg gratings held at different temperatures serving as the end mirrors of a Ti:sapphire laser made possible very narrow output linewidth and enabled easy optimization of the laser output.
