Artistic impression of how ultrasound-generated bubbles inside biological tissue can reduce optical scatter, allowing higher-quality laser microscopy at greater depths.
The use of on-chip nonlinear waveguides that can convert 1.5-μm wavelength signals into the 2-μm region brings new opportunities for expanding the bandwidth of optical communications.
Ultrasound-induced gas bubbles in tissue can temporarily minimize optical scattering, enabling laser light to be focused at greater depth for higher-resolution imaging.
Several research groups have now succeeded in achieving lasing in free-electron lasers (FELs) driven by compact plasma wakefield accelerators. In the future, the approach may ultimately lead to a new breed of much smaller, more affordable FELs.
Organic LEDs based on acceptor–donor–acceptor molecules Y11, IDSe-4Cl and COTIC-4F are shown to be highly effective emitters of short-wave infrared light.
Researchers show that resonant coupling of light pulses with excitonic transitions affects the optimal time difference between pulses for sum-frequency generation and four-wave mixing in monolayer WSe2.
High-speed, high-resolution optics-based printing typically requires femtosecond pulsed lasers. We demonstrate optical printing using indigo-blue laser diodes and a red continuous-wave laser, achieving a peak printing rate of 7 × 106 voxels s–1 at a voxel volume of 0.55 µm3.
