Raman spectroscopy offers a powerful alternative analytical method for the detection and identification of lipids/oil in biological samples, such as algae and fish. Recent research in the authors' groups, and experime...

A compact and efficient green laser light at 538 nm produced by self-sum-frequency-mixing of both fundamental infrared laser waves (1061 and 1091 nm) in Nd:GdCa(4)O(BO(3))(3) (Nd: GdCOB) crystal is demonstrated. With ...

Frequency doubling of mode-locked frequency-tunable CO laser emission in high quality 17-mm long ZnGeP(2) nonlinear optical crystal was studied. The internal efficiency of frequency doubling exceeded 25%, which was ob...

Absorption and fluorescence spectra and fluorescence lifetime measurements are presented for Ce(3+):Er(3+):Yb(3+):YVO(4) crystals and compared to the corresponding data for Er(3+):Yb(3+):YVO(4) crystals. These results...

An efficient system for generating the four-wave mixing (FWM) effect in a short length of a highly nonlinear fiber (HNLF) is demonstrated using a ring configuration, which to our knowledge is the first of its kind to ...

We report a fully-fiberized, pulsed ytterbium-doped master oscillator power amplifier (MOPA) for materials processing applications providing both a temporal pulse and spatial beam shaping capability operating at a max...
