A dual-pump, electronic-resonance-enhanced (ERE) coherent anti-Stokes Raman scattering (CARS) technique for the measurement of minor species concentrations has been demonstrated. The frequency difference between a visible Raman pump beam and Stokes beam is tuned to a vibrational Q-branch Raman resonance of the nitric oxide (NO) molecule to create a Raman polarization in the medium. The second p...

introduction: trichophyton rubrum is one of the most common species of dermatophytes which affects superficial keratinous tissue. it is not especially virulent but it can be responsible for considerable morbidity. although there are different therapeutic modalities to treat fungal infections, clinicians are searching for alternative treatment because of the various side effects of the present t...

A static modulated Fourier transform spectrometer composed of a modified Sagnac interferometer was implemented for real-time remote sensing the spectral property changes in solid dye. In spectrum obtained from spectrometer, relationship between resolution and dependent factors discussed to prevent aliasing. As target material, solid-state dye rhodamine-6G fabricated laboratory. When an intense ...

We present an in-depth investigation of laser-induced grating spectroscopy (LIGS) for temperature measurements in practical applications using a narrow-band dye laser with 760 nm wavelength and pulse duration 8 ns as the source pump beams creating grating. The was set to be either resonant transition from band O2 generation thermal LIGS or nonresonant purely electrostrictive LIGS. Signals were ...

Port-wine stain (PWS) is one of the representative cutaneous vascular malformations. Pulse dye laser (PDL) a traditional treatment method to treat PWS. A newly developed potassium-titanyl-phosphate (KTP) laser, DermaV, can be irradiated with single pulse, or pulse divided into several sub-pulses in length 0.3ms 1.5ms. This study aimed investigate skin response KTP and PDL according different du...

Dye-laser technology has seen very significant progress over the last 39 years since the first demonstration of this device technology. Dye lasers offer efficient emission in the visible and near-infrared bands by direct generation of laser light. The initial emphasis was on the liquid-phase technology, and is the one very successful liquid laser. More recently the research emphasis has been so...
