WebSep 9, 2024 · where s is the object distance, s’ is the image distance, f is the focal length of the lens and z R is the Rayleigh range of the laser beam. Object and image distances refer to the locations of the beam waist before and after the lens. Several important insights can be gleaned by analyzing this equation. WebOct 12, 2011 · This Demonstration simulates Gaussian beam propagation and transformation by two lenses. With different placement of the lenses the final beam waist (radius of the narrowest part) is different. In this …

It is also possible to measure the spot size (eg., … WebAug 17, 2011 · Applying the formula once more to calculate the waist yields a waist radius of 3.2 microns, which is quite small indeed. A "safe" laser pointer might have a power of 1 mW. The peak intensity is equal to $2P/\pi w_0^2$, so before the lens the peak intensity is about 600 W/m^2. After the lens it is about 100000 times larger. So, to summarize:
WebCompare this with 1/e 2 radius λ/ (π NA) ≈ 1.0 μm for an ideal Gaussian beam, potentially rising to 2 μm if the quality factor M 2 is as high as 2. A reasonable estimate for the 1/e 2 … Web5. Gaussian beam/lens The laser resonator shown in the gure below with z = 0 located at the at mirror and its output impinges on a lens of focal length 10cm. Assume the beam waist size, w0=0.5mm; laser wavelength, λ= 632.8nm; and distance of the lens to laser output mirror, d=50 cm. (a) What is the far- eld beam divergence in mrad? Solution:
