Lasers

Light Conversion is celebrating the production of the 2000th PHAROS femtosecond laser. The celebration marks a long journey of continuous development of the company‘s first femtosecond laser.

Light Conversion’s growth speaks for itself. The 1000th PHAROS was shipped in 2019, and only three years later, they mark the 2000th unit.

Now, the PHAROS laser has a model that features a 4 mJ pulse energy,​​ as well as a model with <100 fs pulse duration — both at 20 W of average power.​​ 

Industry and science both show high demand for PHAROS for material processing, spectroscopy, microscopy, and many other applications. This high demand will not stop any time​​ soon!

CNI Optoelectronic Technology Co., Ltd. (CNI) has launched multi-wavelength solid-state light engines (SLEs) for applications such as excitation of GFP/FITC, DAPI, YFP, mcherry, Cy3, Cy5, and spectrally​​ similar fluorophores. Wavelength combinations can be selected according to requirements.

Features include:

  • Power drive integrated in one system

  • Number of combined channels: 1–6 optional

  • Standard wavelengths: 365, 473, ​​ 525, ​​ 642 nm

  • Optional wavelength range: 260–1650 nm

  • Color temperature: 3000 K for standard wavelengths (can be customized)

  • Single wavelength or multi-wavelength combination output

A research team has demonstrated that non-amplified femtosecond laser systems delivering 40–500 pJ​​ individual pulses are sufficient for inducing localized cross-linking reactions within hundreds of nanometers in cross sections of non-photosensitized polymers.

The FLINT oscillator from Light Conversion was employed for the experiments for this research.

Another image from Tony Hallas shows the Triangulum Galaxy (M33), located about 2.73 million light years away from Earth.​​ This image was photographed over 11 hours, using​​ Chroma Technology's​​ astronomy filters.

Image for Improving Signal-to-Noise Ratio

Signal-to-noise ratio (SNR or S/N) is the ratio of the power of a signal (desired input) to the power of the background noise (undesired input).

Typically, the signal power can’t be​​ controlled or increased. Therefore the path to improving the SNR is to reduce/filter the background noise.

Iridian Spectral Technologies Ltd​​ is a diversified optical filter manufacturer that is an international leader in filter design and manufacture especially for application in the fields of fiber optic​​ communications,​​ biomedical optical​​ spectroscopy,​​ 3D entertainment, and​​ aerospace.

 

Detectors

In a recent paper, researchers experimentally demonstrated a​​ fundamental cryptographic primitive, where quantum Weak Coin Flipping (WCF) can achieve theoretically perfect information security over modern communication networks.​​ 

Such a demonstration was made possible by using high-efficiency Superconducting Nanowire Single-Photon Detectors (SNSPDs). The team used​​ ID Quantique’s​​ ID281 Series SNSPD system.

ID Quantique (IDQ) announces enhancements to the ID281 series of Superconducting Nanowire Single-Photon Detectors (SNSPDs).​​ The best in single-photon detection is getting even better.

First and foremost, the new-recipe ID281 SNSPDs exhibit a considerably reduced timing jitter (uncertainty in the detection pulse arrival time, as low as < 25 ps FWHM) and recovery time (time for​​ the detection efficiency to reach 50% of its peak after a detection event, typically < 30 ns). This means you can see more individual photons, faster and with greater precision.

Non-destructive testing (NDT)​​ covers all the techniques used to analyze something without causing damage. Most NDT methods use visual inspection or x-ray analysis. NDT has been used in a wide variety of fields, such as food, automotive, aerospace, and semiconductors.

Photonis offers OEMs and integrators intensified cameras from Ultra-Violet (UV) to Near Infrared (NIR), as well as Short Wave Infrared cameras (SWIR) or Long Wave Infrared (LWIR) to support these challenges.

Systems

Image for SCI Technology

Äpre Instruments’s Spectrally Controlled Interferometry (SCI) combines:

  • Coherence-controlled illumination

  • Vibration-tolerant data​​ acquisition

  • REVEALTM data analysis and reporting

Watch an introductory video about Äpre SCI, and learn how to streamline your metrology process.

Upgrading​​ an old interferometer is one-third the cost of buying a new one. Watch Äpre’s video for a quick explanation of why you should upgrade your interferometer​​ instead of buying new.

To determine if your interferometer needs an upgrade, download Äpre’s free “Optical Production Control Field Guide.”

For more answers to other common questions regarding interferometer upgrades, refer to the FAQ page on Äpre’s website.
