Progress in Sub-Micrometer Periodicity of Quasi-Phase Matching Structures
- 2009
-
Ingår i: 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. 906-907
-
Konferensbidrag (refereegranskat)abstract
- We report on the progress in fabrication of sub-micrometer ferroelectric domain gratings in KTiOPO4. Periods as short as 565 nm have been created in the bulk of the crystal by electric-filed poling.

Terahertz Near-field Imaging : Rigorous Model for Interpreting "Antenna approach"
- 2009
-
Ingår i: 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. 3027-3028
-
Konferensbidrag (refereegranskat)abstract
- Classical Mie theory fails to explain high resolution of a terahertz imaging system exploiting scattering of the near-field radiation. Reported numerical model confirms the feasibility of an antenna model which proves the enhanced resolution.

Spectral Properties of a Mirrorless Optical Parametric Oscillator
- 2009
-
Ingår i: 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. 1676-1677
-
Konferensbidrag (refereegranskat)abstract
- In this work we show how the spectral properties of the pump are transferred to signal and idler in a mirrorless optical parametric oscillator and that the idler properties strongly depend on the grating vector.

Nonlinear refractive indices in undoped and Yb-doped KT(WO4)(2) T=Y, Yb, Gd, Lu crystals
- 2009
-
Ingår i: 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. 3045-3046
-
Konferensbidrag (refereegranskat)abstract
- Nonlinear index was investigated in undoped and Yb-doped monoclinic double-tungstates for E parallel to N-m and E parallel to N-p polarized 819 nm light. Anisotropic n(2) with maximum for E parallel to N-m in all investigated compounds is proportional to the rare earth ion polarizability.

Study of a Narrowband Optical Parametric Oscillator at Degeneracy with a Transversely Chirped Bragg Grating
- 2009
-
Ingår i: 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
-
Konferensbidrag (refereegranskat)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.

All-fiber laser cavity dumping
- 2009
-
Ingår i: 2009 Conference on Lasers and Electro-Optics and 2009 Conference on Quantum Electronics and Laser Science Conference, CLEO/QELS. - Washington, D.C. : IEEE. - 9781424451845 ; , s. 463-464
-
Konferensbidrag (refereegranskat)abstract
- Cavity dumping of a fiber laser is demonstrated. A microstructured fiber with an electrically driven internal electrode is used for intracavity polarization rotation with nanosecond risetime. The optical flux can be dumped within one roundtrip.
