You are an optical engineer looking for a way to make sure than the laser light emitted by your Nd:YAG laser can go forward but cannot be reflected back into the laser cavity.

(a) Name the device you need.

(b) Find one such device through web-search. The maximum budget is $1,000. Specify the manufacturer and the model number.

(c) Investigate the technical specification of the device and find what % of the reflection can return to the laser through the device typically.

Expert Solution

(a) Optical isolator can be used there as it transmits the light in only one direction and it is typically used to prevent from unwater reflection or feedback into the optival cavity.

(b) Manufacturer - THORLABS

Port number : IO-2.5-1064-VLP

(c) center wavelength- 1064 nm

isolation upto 55 dB

power densities up to 20 kW/cm2

Transmission > 90%

An optical engineer is calibrating a spectrometer that uses a diffraction grating to separate light in order of increasing wavelength (λA, λB, and λC). He observes three distinct first-order spectral lines at the following respective angles θm (where m denotes order). θ1 = 12.8°, θ1 = 13.9°, θ1 = 15.3° (a) If the grating has 3,740 grooves per centimeter, what wavelength (in nm) describes each of these spectral lines? at θ1 = 12.8° λA = nmat θ1 = 13.9° λB...

Your buddy comes to you with a sure-fire way to make some quick money and help pay off your student loans. His idea is to sell T-shirts with the words “I get” on them. “You get it?” He says, “You see all those bumper stickers and T-shirts that say ‘got milk’ or ‘got surf.’ So this says, ‘I get.’ It’s funny! All we have to do is buy a used silk screen press for $9,000 and we are in business!”...

3. Radio telescopes are often much larger in diameter than optical (i.e. visible light) telescopes; some of the larger ones have diameters of 100 meters, while the largest optical telescopes are only about 10 meters in diameter. Assume that radio telescopes observe at wavelengths around 1 cm, which is about 20,000 times longer than the wavelengths of visible light. a) Explain why these large radio telescopes have much greater light-gathering power than large optical telescopes. Explain what quantities light-gathering power...
