Design for an optical cw atom laser.
A new type of optical cw atom laser design is proposed that should operate at high intensity and high coherence and possibly record low temperatures. It is based on an "optical-shepherd" technique, in which far-off-resonance blue-detuned swept sheet laser beams are used to make new types of high-density traps, atom waveguides, and other components for achieving very efficient Bose-Einstein cond...
متن کاملPulsed, single-frequency, ring laser with a holographic output coupler.
A unidirectional, passively Q-switched, 2.05-μm Ho:YLF ring laser providing single-frequency, sub-mJ-energy, 100-200-ns-long laser pulses at a kHz rate is reported. The wavelength selection and "coarse" spectral narrowing is performed by utilizing a volume Bragg grating as a resonant, narrowband output coupler operated at a small angle away from normal incidence. Pulsed operation of the Ho:YLF ...
متن کاملOutput of a pulsed atom laser
The experimental breakthrough to Bose-Einstein condensation with small numbers of atoms in magnetic traps [1] has raised much interest in the properties of mesoscopic quantum gases. Bose-Einstein condensates with atoms in a single magnetic sublevel have been studied experimentally and theoretically. The recent experimental and theoretical investigations of interference between two independent B...
متن کاملA widely tunable dual-wavelength CW Ti:sapphire laser with collinear output.
We report a collinear output and tunable dual-wavelength CW Ti:sapphire laser with a simple cavity configuration. The wavelength splitting range is easily tuned from 10 nm to 110 nm, which provides 56 THz bandwidth for terahertz generation. The total output power of two colors with the spatial mode of TEM(00) is between 700 mW and 300 mW, for small and large wavelength splittings, respectively,...
متن کاملResonator with variable-reflectivity output coupler.
A novel resonator is proposed, in which the polarizing properties of standard grating and polarizing components (such as Brewster angle windows) inside the cavity are used to vary continuously the ouput coupling over a wide range of values. An analysis of the polarization properties of the modes of such a resonator is presented, and practical suggestions are made about the choice of the polariz...
