A laser pulse with wavelength 515 nm contains 4.40 mJ of energy. Question: How many photons are in the laser pulse? Can someone please walk me through the steps? I have tried to solve this multiple times, but the 2 answers I thought were for sure it are A: 2.21 x 10^22 photon B: 4.40 Joules X (1 photon/3.860x10^-19 Joules) They were both wrong.
My problem states: A nitrogen gas laser pulse with a wavelength of 337 nm contains 3.83 mJ of energy. How many photons does it contain? When I plug in the equations to my TI89 Titanium calculator, the answer I get is 6.49x10^-23 but your answer and the answer in my text is 6.49x10^15. Why? What am I plugging in wrong?
4.8 He-Ne Laser The He-Ne laser system energy levels can be quite complicated, as shown in Figure 4.58. There are a number of lasing emissions in the laser output in the red (632.8 nm), green (543.5 nm), orange (612 nm), yellow (594.1 nm), and in the infrared regions at 1.52 μm and 3.39 μm, which give the He-Ne laser its versatility. The pumping mechanism for all these lasers operations is the same, energy transfer from excited He atoms to Ne...
