This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

High power photonic bandgap fiber lasers

Shirakawa, Akira; Chen, Meishin; Xinyan Fan; Ueda, Ken-ichi; Olausson, Christina B.; Lyngso, Jens K.; et al. (1 more)

16th Opto-electronics and Communications Conference — 2011, pp. 55-56

Rare-earth doped photonic bandgap fibers enables novel gain profile engineering to realize laser operations at new wavelengths which have never been possible by the conventional fiber lasers. Our recent activities will be reviewed.

Photonic bandgap fiber lasers and multicore fiber lasers for next generation high power lasers

Shirakawa, A.; Chen, M.; Suzuki, Y.; Sato, K.; Fan, X.; Tünnermann, H.; et al. (5 more)

Specialty Optical Fibers 2014 — 2014

Photonic bandgap fiber lasers are realizing new laser spectra and nonlinearity mitigation that a conventional fiber laser cannot. Multicore fiber lasers are a promising tool for power scaling by coherent beam combination. © 2014 OSA.

High power ytterbium fiber lasers at extremely long wavelengths by photonic bandgap fiber technology

Shirakawa, Akira; Olausson, Christina B.; Maruyama, Hiroki; Ueda, Ken-ichi; Lyngsø, Jens K.; Broeng, Jes

Optical Fiber Technology — 2010

Yb-doped fiber laser operating at the long-wavelength edge (1150–1200nm) of the broad gain spectrum has been investigated for yellow-orange sources. Power scaling in this region has been recently achieved by Yb-doped solid-core photonic bandgap fibers, in which the Yb gain profile is engineered

High power ytterbium fiber lasers at extremely long wavelengths by photonic bandgap fiber technology

Shirakawa, Akira; Chen, Meishin; Ueda, Ken-ichi; Olausson, Christina B.; Lyngso, Jens K.; Broeng, Jes

Ieee Winter Topicals 2011 — 2011, pp. 183-184

Yb-doped photonic-bandgap fiber sources operating at the long-wavelength edge of the gain band are presented. Novel gain-profile engineering by the bandpass distributed filtering enables amplified-spontaneous-emission-free gain and power scaling to >15dB and >160W at 1178nm.
