Efficient superfluorescent light sources with broad bandwidth
, 1997 We demonstrate various efficient broad-band light sources at ~1µm wavelength with a 3dB bandwidth of up to 65nm at 108mW output power, based on rare-earth doped silica fibers and a simple adjustable spectral ...

Enhanced light output power of quantum cascade lasers from a tilted front facet.
Optics Express, 2013 We present a technique for enhancing the light output power of quantum cascade lasers (QCLs) by tilting of the front facet, which leads to a change of the modal reflectivity, resulting in an asymmetric light intensity distribution along the laser cavity.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Efficient generation of >2 W of green light by single pass frequency doubling in PPMgLN
, 2007 We report 32% efficient frequency doubling of single frequency 1029 nm light to green light at 514.5 nm using a single pass configuration. A congruent composition, periodically poled magnesium doped lithium niobate (PPMgLN) crystal of 50 mm length was ...
