Researchers Shrink Titanium-Sapphire Laser to Chip-Scale
Making a jump from tabletop to the microscale, engineers at Stanford University have built a titanium-sapphire (Ti:sapphire) laser on a chip. According to the researchers, the prototype is four orders of magnitude smaller (10,000×) and three orders less expensive (1,000×) than any Ti:sapphire laser ever produced.

Cytometer Detects Rare Cancer Cell Subpopulations Concurrently
A new flow cytometry system could help scientists develop more targeted, personalized strategies for treating cancer by enabling them to follow disease progression and therapeutic response in different cancer cell subpopulations simultaneously. The technique, called diffuse in vivo flow cytometry, was developed by researchers at Northeastern University and Dartmouth College. The method noninvasively detects fluorescent protein-expressing circulating tumor cell subpopulations and tumor cell clusters within the bloodstreams of small animals.

Cellphone-Based Raman Spectrometer Recognizes Materials in Minutes
Scientists, medical personnel, and others will be able to quickly identify drugs, chemicals, and biological molecules with a handheld device for Raman spectrometry invented by a team at Texas A&M University. The portable Raman spectrometer is suitable for use in remote settings where laboratory-based spectrometers are impractical due to their large size, cost, and power demands.

How to Improve Laser Applications Using Freeform Optics
Wed, Sep 4, 2024 10:00 AM - 11:00 AM EDT
This presentation provides a landscape of the freeform concept, design, product, and module solutions that are available for managers and designers of laser systems and applications that must deliver a performance enhancement that is difficult to obtain with conventional optics. Freeform optics are an elegant solution for beam shaping and aberration correction and allow optimization of laser applications. However, freeform optics are often regarded as difficult to design, difficult to incorporate into optical systems, expensive to make, and limited in optical performance. As a result, they occupy a small niche in the photonics industry. This webinar shows that there are easy, cost-effective ways to design, manufacture, and integrate solutions for high-grade, high-performance, fused silica freeform optics to enhance laser systems and applications. Kidd shares examples of some of the most prevalent and important laser applications to show the technical and financial impact of using freeform optics solutions. These include coherent beam combing for laser-induced fusion and other directed energy applications as well as blue laser beam shaping for the welding of lithium-ion batteries and other electric vehicle components. Presented by PowerPhotonic.
