We observed the interference spectrum that depends on the carrier-envelope phase using a few-cycle laser pulse. The phenomenon is based on the interference between the second and third harmonics generated from a ZnO thin film.
We demonstrate a 120-mW hand-held ultraviolet laser at 0.355 mum by attaching a monolithic wavelength converter at the output end of an optical fiber which is delivering a near-infrared laser light at 1.064 mum.
23 W, single-mode linearly-polarized 0.4 nm linewidth CW generation is achieved in a polarization-maintaining fiber Raman cavity pumped by a linearly-polarized Ytterbium fiber laser and applied to 3 W 589 nm second harmonic generation in MgO-PPLN.
A picosecond single-mode, linearly polarized fiber source producing 176 W of average power was employed to generate up to 80 W average power at 530 nm by frequency doubling through a single LBO crystal.
We present new results on the use of low-loss, deeply modulated waveguides to enhance the flux of high harmonic emission at short wavelengths. This is achieved by quasi-phase matched frequency conversion to increase the coherence length.
