Query: High-Power, Fiber-Laser-Based Source for Magic-Wavelength Trapping in
  Neutral-Atom Optical Clocks   We present a continuous-wave, 810 nm laser with watt-level powers. Our system
is based on difference-frequency generation of 532 nm and 1550 nm fiber lasers
in a single pass through periodically poled lithium niobate (PPLN). We measure
the broadband spectral noise and residual intensity noise to be compatible with
off-resonant dipole trapping of ultracold atoms. Given the large bandwidth of
the fiber amplifiers, the output can be optimized for a range of wavelengths,
including the strontium clock-magic wavelength of 813 nm. Furthermore, with the
exploration of more appropriate nonlinear crystals, we believe there is a path
toward scaling this proof-of-principle design to many watts of power, and that
this approach could provide a robust, rack-mountable trapping-laser for future
use in strontium-based optical clocks.
