Laser Innovations provides sales and support of Spectra Physics VSL-337-Si nitrogen laser systems and laser plasma cartridges. We also support the VSL-337ND and VSL-337i from Spectra Physics, Thermo Laser Science, LSI and Bruker Daltronics. We are your best source of VSL-337 nitrogen laser and laser plasma cartridge modules anywhere.The effects of pulsed nitrogen gas laser emission (337.1 nm wavelength) were studied on human skin. The laser provides high-intensity monochromatic UVA radiation and can elicit delayed erythema in an actual exposure time of about 1 msec (105,000 pulses, each lasting 10 nsec, delivered over 210 sec).The nitrogen laser, first demonstrated in 1963, was the subject of much interest in the 1970s and early 1980s because it produced nanosecond pulses of 337.1-nm ultraviolet light, a wavelength ideal for pumping dye lasers.Solution for Given the wavelength of light output by each of the following lasers, which laser produces light with the highest frequency? Laser Wavelength…Part C 337.1 nm (wavelength of a nitrogen laser) Express your answer using three significant figures. Submit My Answers Give Up Provi F8 59 5 Posted 2 years ago. Nitrogen laser produces a radiation at a wavelength of 337.1 nm. If the number of photons emitted is 5.6 × 1024, calculate the power of this laser.

Cutaneous effects of pulsed nitrogen gas laser irradiation.

The equation you should use is c = ( wavelength x frequency) (3.0 x 10^ 8 m/s) = ( 337.1) ( frequency) ---->> divide most side by 337.1 8.9 x 10^5 Hz or ( 1/s) = frequency Im supposing the wavelength unit is in meters cuz you didnt specify Plus you can check you answer by plug it back into the equation and see if it gives you any of values youCalculate the energy of a photon of electromagnetic radiation at each of the following wavelengths. 337.1 nm (wavelength of nitrogen laser). Answer in J. Thank you :) Answer Save. 3 Answers. Relevance. kartik. 1 decade ago. Favorite Answer. use E=hc/wavelenth. h= 6.64 * 10^-34 and. e = 1.6 * 10^-16.Properties of Nitrogen laser: Nitrogen lasers emit radiation in the Ultra-Violet (UV) region of the electromagnetic spectrum, at a wavelength of 337.1 [nm]. Very simple and cheap laser. Pulse with very high peak power - up to few Mega-Watts. Pulse frequency - up to 1,000 [Hz] - limited by heating effects. Pulse length is of the order of 10 [nsec].A nitrogen laser is a gas laser operating in the ultraviolet range (typically 337.1 nm) using molecular nitrogen as its gain medium, pumped by an electrical discharge. The wall-plug efficiency of the nitrogen laser is low, typically 0.1% or less, though nitrogen lasers with efficiency of up to 3% have been reported in the literature.

MALDI and Biotech Push Nitrogen Laser Development - Tech

Nitrogen molecule falls from energy level E3 energy level E2 (called lower laser level LLL) by emitting a photon of ultraviolet light of wavelength 337.1 nm. The lifetime of the upper energy level is less than the lifetime of the lower energy level. The output of the Nitrogen laser is in the form of pulses i.e., nitrogen laser is a pulsed laser.Nitrogen laser produces a radiation at a wavelength of 337.1 nm. If the number of photons emitted is 5.6×1024, calculate the power of this laser.Question: A. 488.0 Nm (wavelength Of Argon Laser)b. 12.24 Cm (wavelength Of Microwave Oven)c. 337.1 Nm (wavelength Of Nitrogen Laser) This problem has been solved!

Answer: 8.ninety x 10¹⁴ Hz

Explanation:

1) Frequency (f) and wavelength (λ) are inversely related.

2) The equation is: f = c / λ, where c is the velocity of light

3) c = Three x 10⁸ m/s in vacUum

4) To make the calculations you need yo use the conversion between nanometers and meters:

1 meter = 10⁹ nanometer

5) Calculations:

f = Three x 10⁸ m/s / 337.1 x 10⁻⁹ m = 8.ninety x 10¹⁴ Hz

Hz is hertz, the SI unit for frequency and it way cycles in line with 2d, that is quantity of waves according to 2d.
