You should never pick the skin after treatment and always protect your skin from the sun. You will not need pain medication before, during or after treatment. The discomfort is brief and minimal, lasting only seconds.

LASER, considered intense monochromatic light in Raman scattering, can give rise to scattered light, which contains one or more sidebands offset by rotational or vibrational energy differences. The sidebands produced include frequencies containing information about the scattering medium, and hence they are used in remote sensing.

The principle behind Raman spectroscopy is that the monochromatic radiation is passed through the sample such that the radiation may get reflected, absorbed, or scattered. The scattered photons have a different frequency from the incident photon as the vibration and rotational property vary. This results in the change of wavelength,, which is studied in the IR spectra.

The degree of freedom (DOF) is defined as a number of independent parameters that determine the configuration of the physical system. Following is the degrees of freedom formula:

Inelastic scattering of photons is similar to the concept of an inelastic collision, which states that the total microscopic kinetic energy is not conserved. In an elastic collision, the transfer of kinetic energy occurs, but the scattering will still be inelastic like in Compton scattering.

For Raman scattering, 3 N is the DOF (for any given chemical compound), where N is the number of atoms in the compound 3 N is DOF because each atom moves in x, y, and z-direction ie; they possess translational, rotational, and vibrational motion.

Raman spectrometer is an instrument that consists of one or more single-coloured light sources and lenses and filters to focus the light and to differentiate the reflected and scattered light, respectively. A prism is used for splitting the light into its components which has a detector to detect the weak light. Later the spectrum is obtained on the monitor to analyze the information.

The difference between the incident photon and the scattered photon is known as the Raman shift. When the energy associated with the scattered photons is less than the energy of an incident photon, the scattering is known as Stokes scattering. When the energy of the scattered photons is more than the incident photon, the scattering is known as anti-Stokes scattering.

How does it work to close the vein? The Nd Yag Laser deliver pulses of light energy which cause the blood within the vein to coagulate eventually destroying the vessel, which is later reabsorbed by your own body. Blood flow will then be redirected to veins deeper below your skin's surface where it should be. Blood Blisters or angiomas/hemangiomas respond well to the Nd Yag Laser, usually with just one or two treatments. Patients with port wine stains and other vascular lesions that have failed other laser treatments have been overwhelmed by the success of the ND Yag Laser treatment.

What can I expect when I get a treatment done? When you come in for a treatment, we will cleanse the area that we are treating then we apply a small amount of ultrasound gel to the skin. You will wear laser safety goggles to shield your eyes. The laser hand piece will touch the skin and feel cool to protect the upper layers of the skin. You will feel some heat and the sensation of an elastic band hitting the skin when the laser is activated. The treatment only takes a few minutes and the laser exposure time only seconds. After the treatment is over we apply some Aloe Vera gel to the skin.

How many treatments do I need? Results vary depending on the patient and the condition that is being treated. Typically patients may need 1-3 treatments for smaller facial veins. Treatment intervals are 4-8 weeks. Larger veins or other vascular lesions may need more treatments.

Is there downtime? Usually there is no down time. Following your treatment, some redness and bruising may occur which can easily be covered by make up if it occurs. Blistering and scarring are rare.

To analyse the Raman effect, the wavelength of the scattered photon is converted to wavenumber. These wavenumbers are plotted on the x-y plane. The wavenumbers are taken along the x-axis and the Raman intensity is taken on the y-axis. The difference between the wavenumbers and the intensity is known as the Raman spectrum.

Raman scattering produces scattered photons with a different frequency depending on the source and the vibrational and rotational properties of the scattered molecules. Raman spectroscopy works on the principle of Raman scattering. It is used to study materials by chemists and physicists. In the olden days, to record spectra, a mercury lamp and photographic plates were used; in modern days, lasers are used. Sir CV Raman was awarded the Nobel Prize for Physics in the year 1930. C V Raman, along with his student K S Krishnan, discovered Raman’s scattering.

similar to Rayleigh scattering, Raman scattering also depends on the polarizability of the molecules. The intensity of Rayleigh scattering is about 10−3 to 10−4 compared to the intensity of the exciting source. The photon’s energy and the state of the molecule after the scattering events are unchanged. In Raman scattering, the frequency of photons presents in the monochromatic light changes when interacted with the vibrational states, or modes, of a molecule.

With the help of the Raman scattering, one can easily say why the sky is blue. This depends on the scattering of blue light because of the presence of the air molecules in the atmosphere. Learn more about applications of Physics concepts with BYJU’S.

ND Yag Laser shines a coherent, monochromatic light on the surface of the skin. Its wavelength is intended to stimulate the skin cells and encourage them to repair and to treat any vascular issues in the skin. The laser combines the ideal laser wavelength with the most flexible parameters to deliver a superior vascular laser system.

Raman scattering is defined as the scattering of photons by excited molecules at higher energy levels. It is also known as the Raman effect. The photons are inelastically scattered, which means that the kinetic energy of an incident particle is either lost or increased and is composed of Stokes and anti-Stokes portions.
