Low group delay dispersion quarter wave retarder
ULTRA-LOW NOISE MICROWAVE SYSTEM
Kauai( UFI Innovations) is a quarter-wave retarder operating over a broad spectral range from 650 to 1400 nm, with a reflectivity of up to about 90 % and a low group delay dispersion below 3 fs ². Its compact reflective design preserves the beam direction and facilitates integration into existing optical setups. It is intended for use in high-performance laser systems, including ytterbium-based sources. www. ultrafast-innovations. com / devices / KAUAI. html
TOPTICA Photonics introduces the X-MMS( X-band Metrological Microwave Solution), a system designed to generate ultra-low-noise microwave signals. Based on a photonic approach, it derives a 9.6 GHz signal from a highly stable optical reference using optical frequency division, enabling high spectral purity and stability. www. toptica. com
Optical Frequency Discriminator
SILENTSYS introduces the OFD-PRO, its next-generation Optical Frequency Discriminator. This system characterizes and stabilizes laser frequency noise, reducing linewidth( FWHM) with enhanced environmental resistance( 40x less temperature impact, 10x less vibration sensitivity), plug-andplay servo-control, and 19-inch rack compatibility. It achieves sub-MHz stabilization over long timescales for 200 THz optical carriers. https:// silentsys. com /
SINGLE-MODE VCSEL
Brightlaser’ s 660 nm single-mode VCSEL excels in precision applications, offering stable linear polarization, high spectral purity, and excellent beam quality. With output power up to 2 mW, a linewidth < 100 MHz, SMSR > 30 dB, and PER > 20 dB, it is ideal for FTIR spectroscopy, medical OCT, and industrial metrology. www. lasercomponents. com / fr / photonics-portal / actualites / vcsel-monomode-a-660-nm-avec-polarisation-stable /
Transparent photopolymer for 3D printing
Boston Micro Fabrication launches BMF Clear, an optically transparent photopolymer resin for micro-precision 3D printing, offering > 90 % light transmittance and micron-level accuracy. Ideal for microfluidics, photonics, and biomedical devices, it enables complex, internally structured components previously unachievable with additive manufacturing. Compatible with BMF’ s 10 µ m and 25 µ m systems, it supports scalable production of micro-optical features like lenses, waveguides, and lab-on-a-chip systems. www. bmf3d. com
