The phrase "a good beam" is correct and usable in written English.
It can be used in contexts related to construction, engineering, or even metaphorically to describe something that is strong or effective.
Example: "The architect praised the design, stating that it featured a good beam that would support the entire structure."
Alternatives: "a strong beam" or "an effective beam".
Therefore, M2 can be treated as a total reflection mirror, while M1 is still acting as a good beam splitter.
"I think I'm most happy with beam just because it always feels really good once you hit a good beam set," she said.
The resonator was designed to achieve a good beam quality for the whole range of operation with a maximum beam parameter product of 15 mm mrad (M2∼45).
A new RF power system with a modified power delivery scheme provides a good beam loading compensation with a high-intensity multi-bunch electron beam.
2.04-kW 1120-nm signalightht with a good beam quality (M2=1.15) is obtained, and the optical conversion efficiency of the composite cavity fiber laser oscillator is about 63% in the experiment.
A negligible confinement loss along with a low dispersion slope (~0.03 ps/km-nm2), relatively low bend loss, and a good beam quality factor (M2~1.17) should make this LMA fiber design attractive for fabrication as a potential candidate suitable for high power, passive applications at the mid-IR wavelength regime.
CO2 lasers generally have an efficiency of 20%%, with a very good beam quality, high precision and high welding speed (Chang et al. 2010).
These bars exhibit a very good beam quality of 5.7°×27.2° (full-width at half-maximum).
Thanks to this peculiar microstructure, the fiber is shown to have an increased Brillouin threshold power and very low bending losses, while preserving a very good beam spatial quality.
The laser pump chamber and resonator were designed and optimized to achieve a high efficiency and good beam quality with a beam parameter product of 16 mm mrad (M2∼47).
"No problems between us, all good," beamed James Oh, 62, the liquor store's Korean-born owner.
