Laser Focus World’s Innovators Awards program celebrates the disparate and innovative technologies, products, and systems found in the photonics market.

Based on the impartial ratings by our judges, awards were assigned in four different levels—Platinum, Gold, Silver, and Bronze—to companies or organizations that demonstrated excellence in a product or technology, an application, or in research and development.

Submissions were judged on originality; innovation; their impact on designers, systems integrators, or users; whether they fulfilled a new market need; leveraged a novel technology; and/or increased productivity.

To celebrate our second annual Innovators Awards Program, Laser Focus World held a webcast ceremony on November 18, 2019, for all honorees. Here in their own words, the 2019 group of honorees provides a look at where we stand on the leading edge of photonics products and applications.

PLATINUM 2019 INNOVATORS AWARDS: PLATINUM-LEVEL HONOREES

LASERS & SOURCES | Hyperion VUV

Hyperion VUV is the first commercial femtosecond laser source to deliver vacuum ultraviolet (VUV) light, allowing researchers to probe material and molecular properties with unprecedented flexibility and on ultrafast time scales. The discrete tunability of the source—a simple computer-selected change of photon energy—provides a powerful capability previously only available at a synchrotron. The ability to easily change the laser wavelength can enhance many experiments. The source is also highly focusable and with the right optics, spot sizes below 10 µm can be obtained. With pulse durations below 250 fs, the source enables researchers to probe ultrafast dynamics of molecules and materials, and a 1 MHz repetition rate enables rapid data collection and avoids space-charge effects.

SOFTWARE | High-Yield Optimization

Traditionally, computer optimization of optical design uses a numerical merit function to represent the simulated system’s optical performance. The conventional design approach maximizes the nominal performance of the design, and then as a separate step adds fabrication tolerances to the nominal parameters so that upon manufacturing, the resulting system still performs to specification. A new method, called High-Yield Optimization, improves on the traditional method by integrating the manufacturing defects into the design process at the start, rather than adding them as a post-design step, producing designs that have superior performance once fabricated.

OPTICS | In-Stock Extreme Ultraviolet Mirrors

Extreme Ultraviolet (EUV) mirrors for use with wavelengths from roughly 10 to 100 nm are used in lithography, nanoscale imaging, and spectroscopy applications. As EUV research expands with the advent of tabletop EUV lasers and laser-like sources, so does the need for off-the-shelf EUV optics in-stock for immediate shipping. The time between ordering an EUV mirror and it shipping is now measured in hours instead of months, which is especially important for quickly repairing broken systems or exploring new ideas for prototyping. This availability significantly impacts designers and system integrators by facilitating trial-and-error and experimentation in EUV systems without the typical huge time investment. Edmund Optics (Barrington, NJ; www.edmundoptics.com)

OPTICS | Highly-Dispersive Ultrafast Mirrors

Highly-dispersive ultrafast mirrors for dispersion compensation is an important part of ultrafast laser systems. However, such mirrors are expensive and may take up to 16 weeks due to the economics of the required coating runs, which makes it difficult to prototype ultrafast systems or conduct research where large quantities are not needed. Now, a standard selection of highly-dispersive ultrafast mirrors at common wavelengths are available for same-day shipping. By making it economically viable to obtain small quantities and eliminating the long lead times for coating runs, this availability helps designers and system integrators prototype and develop ultrafast sources.
