Because of this property, a Gaussian laser beam that is focused to a small spot spreads out rapidly as it propagates away from that spot. To keep a laser beam very well collimated, it must have a large diameter.

The peak intensity is thus exactly twice the average intensity, obtained by dividing the total power by the area within the radius w(z).

polaris is nice with the pass thru and the rgb is helpful for active application ID'ing at work. At play I'd argue it has limited practicality unless you are doing

Looks wise it is nice to have the polaris as a compliment to the balance of the cue ecosystem. with the release of the qi charging mats...you may want to consider that if that is your preferred direction.

The geometry and behavior of a Gaussian beam are governed by a set of beam parameters, which are defined in the following sections.

COMSOL Gaussianbeam

where w(z) is the radius at which the field amplitude and intensity drop to 1/e and 1/e2, respectively. This parameter is called the beam radius or spot size of the beam. E0 and I0 are, respectively, the electric field amplitude and intensity at the center of the beam at its waist, that is E0 = | E(0,0) | and I0 = I(0,0). The constant is the characteristic impedance of the medium in which the beam is propagating. For free space, .

Also for a desk look at the Ikea Linnmon if you are on a student budget! I have a huge 59" and another smaller 39" on the other side to create an L shape.

laguerre-gaussian modes

These extended mouse pads are nice for people with wider keyboards that offset the mouse pad too far to the side. You can gain a little back by having them together. I have used quite a few of these over the past several years, and I do like the MM300. I bought that one for the unique color scheme, but it might not be for everyone. It can be found for a very good price at a lot of places.

For a Gaussian beam, the complex electric field amplitude, measured in volts per meter, at a distance r from its centre, and a distance z from its waist, is given by

In optics, a Gaussian beam is a beam of electromagnetic radiation whose transverse electric field and intensity (irradiance) distributions are described by Gaussian functions. Many lasers emit beams with a Gaussian profile, in which case the laser is said to be operating on the fundamental transverse mode, or "TEM00 mode" of the laser's optical resonator. When refracted by a lens, a Gaussian beam is transformed into another Gaussian beam (characterized by a different set of parameters), which explains why it is a convenient, widespread model in laser optics.

personally i use both :) its nice to have the mm300 under the keyboard and the mouse either way whatever you choose, i have to highly recommend the extended antifray mat.

Besselbeam

That looks sweet dude, I have the mouse plugged into the mousepad it looks like a complete mess, all bunched up, excess wire cable tied to make it even more noticeable... I think you just solved my problem by plugging it into the pc!

Laser beam quality is quantified by the beam parameter product (BPP). For a Gaussian beam, the BPP is the product of the beam's divergence and waist size w0. The BPP of a real beam is obtained by measuring the beam's minimum diameter and far-field divergence, and taking their product. The ratio of the BPP of the real beam to that of an ideal Gaussian beam at the same wavelength is known as M² ("M squared"). The M² for a Gaussian beam is one. All real laser beams have M² values greater than one, although very high quality beams can have values very close to one.

Gaussianbeamq parameter

For a Gaussian beam propagating in free space, the spot size w(z) will be at a minimum value w0 at one place along the beam axis, known as the beam waist. For a beam of wavelength λ at a distance z along the beam from the beam waist, the variation of the spot size is given by

The mathematical function that describes the Gaussian beam is a solution to the paraxial form of the Helmholtz equation. The solution, in the form of a Gaussian function, represents the complex amplitude of the electric field, which propagates along with the corresponding magnetic field as an electromagnetic wave in the beam.

I have both, but you are in two different categories here with rather different products. The MM800 is a show toy to go with your K95 platinum with the same light rail. I am using it now, bit I am not sure I would without the glass desk to amplify the effect. It is the least consequential peripheral I own, but if the light is appealing, get it. You will also need to decide between the hard surface and soft. I tried the hard a while back and was too slick for my liking. Took another go with the cloth over the holidays a liked it. It was only meant to be part of the seasonal decorations, but I am still using it.

Hello, right now I'm having a really rough time deciding if should get the MM800 Polaris or the MM300. I really like the RGB effects on the Polaris but I feel that it may be a bit pricey and that it will add another cable to my setup. The MM300 looks nice as well, and I really like that it's extended, but I don't really know if the fact that it's extended will make it better. Right now my desk is pretty small but I'm planning on getting a new and bigger one. And since I'm a student I need room for schoolwork and I feel like I will lose the majority of space I have on my desk.

The parameter w(z) approaches a straight line for . The angle between this straight line and the central axis of the beam is called the divergence of the beam. It is given by

Since the gaussian beam model uses the paraxial approximation, it fails when wavefronts are tilted by more than about 30° from the direction of propagation[1]. From the above expression for divergence, this means the Gaussian beam model is valid only for beams with waists larger than about 2λ/π.

The peak intensity at an axial distance z from the beam waist is calculated using L'Hôpital's rule as the limit of the enclosed power within a circle of radius r, divided by the area of the circle πr2:

The complex beam parameter plays a key role in the analysis of gaussian beam propagation, and especially in the analysis of optical resonator cavities using ray transfer matrices.

It seems like you need to figure out what you need for your space, rather than pros and cons, but you'll have to work that out.

I run my M65's cable along the MM800 cable with a Velcro tie and leave myself a bit of slack. Doesn't really feel like theres two cables between the two of them!
