Liquids and Gels Fill Gaps in Tricky Optical Designs

As anyone who has ever worked with an alexandrite laser can attest, its lasing medium demands respect. “It has about every problem a laser engineer can imagine,” said Josef Höffner,...

Confocal and multiphoton microscopy are commonly used to provide 3D-resolved images of in vitro or in vivo tissue samples without physical sectioning. But there are also inherent trade-offs in the...

It is a rare event when a successful experiment in basic research makes it to the evening news. In December 2022, the U.S. secretary of energy announced a breakthrough in laser-based nuclear fusion....

Many common spectroscopic measurements require the coordinated operation of a detection instrument and light source, as well as data acquisition and processing. Integration of individual components...

Unlike an edge emitter, a VCSEL has a maximum operating power that is not limited by catastrophic optical damage of the exit aperture because its aperture is larger and its PN junction does not...

Optical fibers are made from either glass or plastic. Most are roughly the diameter of a human hair, and they may be many miles long. Light is transmitted along the center of the fiber from one end...

This presentation shines a spotlight on the transformative laser technology known as coherent beam combining (CBC). While this technology has been known for decades, it only recently has been...

For spectroscopic applications, quantum cascade lasers (QCLs) provide coherent, polarized mid-IR radiation with spectral power densities in the 10- to 100-mW range. These properties are very...

Fluorescence microscopy has revolutionized life sciences by enabling researchers to study biological samples with exceptional precision. New excitation and illumination light sources and scientific...

High-volume manufacturing of products such as smartphones, medical devices, and semiconductors all require laser processing during the manufacturing process. Industry and consumer demand for smaller,...

A probe card is a testing device used in the semiconductor manufacturing industry to evaluate and test the electrical characteristics of integrated circuits (ICs) on a wafer. Its primary function is...

A crystal, glass, or quartz slicing and cutting machine is a specialized piece of equipment used in the manufacturing process to precisely cut and slice materials such as crystals, glass, and quartz...

Laser powder bed fusion (LPBF) is a type of additive manufacturing (AM) or 3D printing technology that uses a high-power laser to selectively fuse or melt layers of powdered material to build up a...

An electro-optic modulator (EOM) is a device used to modulate the amplitude, phase, or polarization of light waves using an external electrical signal. Electro-optic modulation is a fundamental...

The new VirtualLab Fusion 2023 thrills with a firework of new features. In this webinar we give an overview of the new features and put them into context with the development strategy and technical...
