Image for Conserving Electricity with Light Conversion Lasers

These days when electric bills are skyrocketing and governments encourage saving​​ energy in every possible way, the relatively low power consumption of​​ Light Conversion​​ lasers might be very advantageous.

The​​ CARBIDE femtosecond laser​​ (6 W, 100 µJ) consumes only 150 W — less than 20% of the power required by a typical toaster (~800 W).

What is more, the CARBIDE is air-cooled. Therefore​​ a​​ chiller is not required.

The more powerful​​ PHAROS femtosecond laser​​ (20 W, 4 mJ) consumes only 600 W — still less than a toaster!

Pulse width is an important parameter of the pulsed laser. The measurement result is an important factor affecting the single pulse energy.

CNI Optoelectronics Tech offers free-space​​ biased photodetectors​​ for​​ monitoring ultrafast,​​ pulsed lasers and measuring their pulse width, rise time, repetition frequency, period, and other parameters. For detecting high speed signals, a 50 Ω load resistor is also recommended.

A collaboration including Light Conversion​​ has​​ demonstrated a compact,​​ high-flux,​​ X-ray source based on irradiation of solid targets by gigahertz and megahertz bursts of femtosecond laser pulses.

The simplicity and relative cost-effectiveness of the presented X-ray source makes it an attractive solution for future applications in ultrafast, x-ray imaging and spectroscopy.

Figure 1(a) shows the scheme of the experimental X-ray generation and detection setup. Laser radiation is​​ delivered by the​​ solid-state femtosecond laser​​ CARBIDE.

Image for New 3D Beam Shaping Methods for Ultrashort-Pulsed Laser Material Processing

Holo/Or has​​ recently published an article about the potential of new 3D beam shaping techniques to enable more productive ultrashort laser material processing. There is discussion of laser glass cutting of curved surface and with chamfers included, channel writing for micro fluidics, scribing on the inside of tubes,​​ and much more.

This article is entitled, “3D beam shaping methods for ultrashort-pulsed laser material processing.”

For more information about​​ these techniques,​​ contact Holo/Or.

 

❂Light Sources

Superlum Diodes introduces 100 mW,​​ SLD-based light sources at 850 nm.

This new MOPA-SLD-850-P100W12 is an SLD-based light source, providing 100 mW PM fiber output power with a smooth, very low-ripple, 12-nm-wide spectrum around an 850 nm center. Its 100 mW output power is at least two times higher than that of any other commercially available fiber-coupled SLD around 850 nm. Moreover, MOPA design significantly relaxes strict limitations on optical feedback, which is inherent to very high power SLDs, thus reducing their applications.

Here is a sampling of seven ground-breaking papers​​ regarding photonic sensing published this year from researchers around the world.

All this research used one or more of the following ID Quantique products:

 

❂Security

ID Quantique (IDQ) is part of a​​ collaboration​​ to establish a new Quantum Key Distribution (QKD) link between Poznan and Warsaw. This link will provide new services for a number of applications,​​ such as telemedicine, medical data transmission, data storage and public services.

In this installation, IDQ deployed their Cerberis XG series, the fourth generation of QKD systems, on the Polish National Research and Education (PIONER) network, operated by the PSNC. The goal of the PSNC is to further integrate its local metro QKD infrastructure, which was developed last year in Poznan, together with this new long-distance Poznan-Warsaw QKD link. The final goal is to interconnect all high performance computing centers in Poland and to establish common access layers to QKD services.​​
