Laser Beams with near-Gaussian Profiles
The sensor is most susceptible to damage from laser beams that approach a Gaussian
profile. Coherent has performed finite element analysis (FEA) thermal modeling on the PMmodel kW sensors, followed by live testing of a fiber laser that is…
…with a direct QBH fiber adapter option 100% of the light is captured, resulting in a Class 1 measurement system. The new PowerMax-Pro kW models will be particularly useful for welding, cutting, drilling, and engraving with high power fiber lasers, CO2 lasers, or solid state lasers. FEATURES · Very…
prevents the joints from warping.
The testing also allowed Coherent | Rofin personnel to recommend a 2 kW fiber laser
(Coherent | Rofin FL 020) with a 300 µm delivery fiber, and focusing optics having a focal
length of 300 mm, as being optimum for this application. This optical…

the oscillator fiber length, and optimized
splice recipes," says Coherent components and defense sales manager Jeff
Wojtkiewicz. "This resulted in a laser with
a 120 ns pulse width, >15 W average
power, and >4 kW peak power--parameters believed to be…
…mm-mrad applications typically are brazing, heat
treating, and laser metal deposition."
Wavelengths in the "9xx" nm wavelength range are slightly shorter than
those of traditional 1 µm lasers such as
disk, fiber, and Nd:YAG. These shorter wavelengths allow better absorption in…
…Corelase). This fiber has a traditional circular core surrounded by another annular cross-section fiber core.
These systems can be built incorporating output from one to
four separate fiber lasers, thus providing total maximum output
powers from 2.5 to 10 kW. No matter what the…
…CO 2 lasers can be applied to the CO laser. Coherent has tested a number of different prototype CO lasers based on the company's waveguide and slab architectures; laser output powers ranged from 20 W to more than 1 kW. The company's first high-power CO laser, which will be shown at LASER World…
