The Better Business Bureau just released some good news: In 2011, consumers consulted the BBB far more often than they did the year before, and they lodged fewer complaints. Surely that's a sign ...
The Better Business Bureau (BBB) is an American private, 501(c)(6) nonprofit organization founded in 1912. BBB's self-described mission is to focus on advancing marketplace trust, [2] consisting of 92 independently incorporated local BBB organizations in the United States and Canada, coordinated under the International Association of Better Business Bureaus (IABBB) in Arlington, Virginia.
When comparing companies that have different ratings, it's important to read the complaints listed on the business' BBB profile, McGovern said. "A lot of times when a rating falls, it is because ...
A distributed feedback (DFB) quantum cascade laser [25] is similar to a Fabry–Pérot laser, except for a distributed Bragg reflector (DBR) built on top of the waveguide to prevent it from emitting at other than the desired wavelength. This forces single mode operation of the laser, even at higher operating currents.
In 2014, Thorlabs acquired Corning Inc.'s line of quantum cascade lasers and entered into a partnership with Daylight Solutions to produce the laser for defense and security applications. [28] In 2015, Thorlabs acquired Pantec's line of Elliptec product line. [29] In 2018, Thorlabs acquired Norland Products' line of fiber optic products. [30]
Connecticut's attorney general has told one of the marketplace's most trusted symbols of consumer protection, the Better Business Bureau, that it risks losing its credibility if it favors those ...
BBB National Programs, an independent non-profit organization that oversees more than a dozen national industry self-regulation programs that provide third-party accountability and dispute resolution services to companies, including outside and in-house counsel, consumers, and others in arenas such as privacy, advertising, data collection, child-directed marketing, and more.
In a standard multiple quantum well laser, the active quantum wells used to generate photons are connected in parallel. Consequently, a large current is required to replenish each active well with electrons as it emits light. In a cascade laser, the wells are connected in series, meaning that the voltage is higher but the current is lower.
