Hübner Photonics and Metamaterial Inc (META) have announced the installation at META (Halifax, Canada) of Hübner’s C-Wave GTR/NIR (green-to-red/near-IR) tunable laser. The new system—the first of its kind in the world, the companies say—features a broad color palette from three tunable Hübner sources. Crucially, it covers a significant gap in the green region that is costly and complex to address with alternative narrow-bandwidth lasers. With the C-Wave GTR/NIR, META will be able to record holograms at any desired wavelength across the entire visible spectrum and, therefore, potentially accelerate holographic product development. The new full-spectrum capability will allow the company to craft full-color red, green, and blue holograms at any combination of wavelengths users may require for optical combiners in augmented reality and head-up display applications.

According to Olympus, its LEXT OLS5100 laser microscope delivers the high levels of accuracy and precision required for submicron 3D observation and surface roughness measurement, and its smart features accelerate and optimize experiment workflows for materials science applications. In three simple steps, the Smart Lens Advisor assists in the selection of the correct objective lens to measure surface roughness. The Smart Experiment Manager helps users handle the planning, acquisition, and analysis phases of their experiments. The microscope scans samples according to a software-generated customized experiment plan, which helps prevent users from missing data or having to redo work. Once users place a sample on the stage and press the start button, the microscope makes all necessary setting adjustments and acquires the data. During analysis, the software’s trend visualization tools help users spot problems. Olympus Corporation of the Americas, 3500 Corporate Pkwy, Center Valley, PA 18034-0610,https://olympusamerica.com

With its new TopWave 405 model, Toptica presents a cost-efficient alternative for the bulky, power-hungry krypton-ion-gas lasers commonly used in lithographic and holographic applications. The TopWave 405 provides 1 W output power at 405 nm and excellent beam quality. Beam diameter and M2, which is typically 1.15, are designed to match the established gas laser parameters, which allows for easy integration without significant changes to the optical system. The higher coherence length—greater than 100 m—is well-suited for stable pattern generation in interference lithography or holography. The all‑semiconductor TopWave 405 draws less than 100 W and does not require water cooling, which reduces the cost of ownership. Fully automated, push-button optimization of the optomechanics and of the output power stabilization allows for easy, hands-off, remote operation via the included graphical user interface or via users’ control software.

Laser Components has developed a beam splitter in which the combined beam of a frequency-doubled laser is divided such that 50% of each of the two wavelengths is split off, even if the beams have different polarizations. The polarization remains the same for both beams. Previously, a beam splitter and a retardation plate were required for that process. The company has been able to combine both functions into one optic, which significantly accelerates setup and maintenance. The original design is for 1030 nm and 515 nm incident beams. However, wavelengths, polarization, and the reflection/transmission ratio can be individually adapted depending on the application.
