The technique works thanks to “surface plasmons” (surface excitations that involve billions of electrons) in the “gap” of the bow-tie gold nanostructures (see figure). When illuminated with the correct frequency of laser light, the surface plasmons can begin to resonate in unison, greatly increasing the local light field intensity. This phenomenon, known as resonant plasmon field enhancement, is already exploited in imaging techniques, such as surface-enhanced Raman scattering, which is sensitive enough to detect individual molecules on a metal surface.

Immediate applications include high-resolution imaging of biological objects, advanced lithography of nanoscale patterns and making X-ray clocks. These exploit a frequency-stabilized femtosecond laser and are being investigated worldwide to replace the current caesium atomic clocks for better time precision.

However, EUV radiation is currently produced in a very complicated process involving the use of amplified light pulses from an oscillator (a source of laser light) to ionize noble gas atoms. The electrons freed during this process are accelerated in the light field and their surplus energy is freed as attosecond (10–18 s) pulses of light of different wavelengths. The shortest wavelengths of light can then be “filtered out” to produce a single EUV pulse.

The team now plans to improve the conversion efficiency of the generated light by modifying the design of their nanostructure — for example, by making 3D cones with sharper tips. These will not only enable higher local field enhancement but also better interaction of the femtosecond light pulses with injected gas atoms. The team will also test the spatial and temporal coherence of the generated EUV light.

Scientists would ideally like to produce EUV light directly from the oscillator without the need for expensive and bulky amplifiers. In this way, EUV-light generation could be simplified and the size of the source significantly reduced to tabletop dimensions. In contrast, current devices usually measure around 2–3 m across. Now, Seung-Woo Kim of KAIST in Daejeon and colleagues have shown that this might be possible.

The researchers report that a bow-tie nanostructure of gold — measuring around 20 nm across — can enhance the intensity of femtosecond laser light pulses by two orders of magnitude. This is high enough to generate EUV light with a wavelength of less than 50 nm directly from a small pulse with an energy of 1011 W/cm2 injected into argon gas (Nature 453 757). The energy needed is about 100 times less than in traditional approaches.

EUV light has a wavelength of between around 5 and 50 nm (100–10 times shorter than that of visible light). It can thus be used to etch patterns at tiny length scales and is ideal for spectroscopic applications because the wavelength is the same as that of many atomic transitions.

A new system to generate coherent extreme-ultraviolet (EUV) light has been developed by researchers in Korea. The device, based on a nanostructure made of bow-tie shaped gold “antennas” on a sapphire substrate, is smaller and cheaper than existing systems and might allow an EUV source the size of a laptop computer to be made. Potential applications for the source include high-resolution biological imaging, advanced lithography of nanoscale patterns and perhaps even “X-ray clocks”.

The G280-IL Series is a cutting-edge solution that leverages the advantages of ironless linear motors. One of the key benefits of these motors is their high precision and accuracy, which are critical factors in many industrial applications. The absence of a ferromagnetic core in the stator eliminates cogging and any interaction between the stator and rotor magnetic fields. This produces incredibly smooth and precise motion, making it an ideal solution for applications where high accuracy and precision are essential. The G280-IL Series delivers unparalleled performance, making it a reliable and efficient solution for applications requiring a high degree of accuracy and precision. Additionally, its compact design and high power density make it ideal for use in applications where space is limited. Whether it is for semiconductor manufacturing equipment, medical devices, or robotics, the G280-IL Series delivers the precision and accuracy that these industries demand.

“This new method of short-wavelength light generation will open doors in imaging, lithography and spectroscopy on the nanoscale,” commented Mark Stockman of the Georgia State University in a related article (Nature 453 731). The spatially coherent, laser-like light could have applications in many areas: spectroscopy; screening for defects in materials; and, if extended to X-ray or gamma-wavelengths, detecting minute amounts of fissile materials for public security and defence.
