Universal grating design for pulse stretching and compression in the 800-1100-nm range
Abstract:
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.

Comparing the stretching vibrational frequency of C≡C triple bonds with that of double and single bonds, it is evident that C≡C triple bonds exhibit a higher stretching frequency than C=C double and C–C single bonds. Similarly, the C≡N triple bond exhibits higher stretching absorption than the C=N...
