  • Tunable narrowband optical parametric oscillator using a transversely chirped Bragg grating
  • 2009

  • Journal article (peer-reviewed)abstract
    • We demonstrate a novel technique for locking and tuning of a near-degenerate nanosecond optical parametric oscillator (OPO) using a transversely chirped volume Bragg grating. When the grating was translated, the OPO signal wavelength could be tuned from 1011 to 1023 nm (3.5 THz). The OPO was based on a periodically poled KTiOPO4 as a nonlinear crystal and was pumped at 532 run with up to 1.9 mJ of energy. The generated signal at an energy of 0.37 mJ had a bandwidth of 0.50 nm and a suppression of broadband background of >30 dB. The demonstrated technique is widely applicable for the construction of narrowband tunable sources. 0 2009 Optical Society of America

  • Study of a Narrowband Optical Parametric Oscillator at Degeneracy with a Transversely Chirped Bragg Grating
  • 2009
  • In: 2009 Conference on Lasers and Electro-Optics and 2009 Conference on Quantum Electronics and Laser Science Conference, CLEO/QELS 2009. - Washington, D.C. : IEEE. - 9781424451845 ; , s. 1672-1673
  • Conference paper (peer-reviewed)abstract
    • We investigate the energy and spectral properties of a narrowband (0.9 nm) optical parametric oscillator, tuneable around the degeneracy point from 1055 to 1066 nm, by usage of a transversely chirped volume Bragg grating.
