We have developed a holographically produced master metallic grating that achieves >91% diffraction efficiency over the wavelength range 800–1100 nm and a maximum diffraction efficiency at 1053 nm greater than 93% when used with TM polarization near the Littrow angle. The near-uniform diffraction efficiency with laser wavelength makes this design attractive for use in chirped-pulse amplification systems employing Ti:sapphire, Cr:LiSAF, or Nd:glass and permits high-fidelity stretching and compression of extremely short (10-fs) pulses.
