Figure 1: PhC structure and optical characteristics. Figure 2: Experimental and computed photoluminescence spectra at various pump powers. Laser oscillation has been demonstrated in a strongly coupled ...

An international collaboration has developed a new diagnostic technique for measuring ultra-short particle beams at STFC's ...

Researchers have demonstrated that laser emissions can be created through the interaction of light and water waves. This 'water-wave laser' could someday be used in tiny sensors or 'lab-on-a-chip' ...

It is possible to operate Sheaumann’s diode laser pumped 2.94 µm Er:YAG MIR-Pac laser product 1,2 in the quasi-continuous-wave (QCW) pulsed mode of operation. This mode is often referred to as ...

Santa Clara, CA and Kyoto, Japan, Jan. 15, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced they have started offering samples of the industry’s smallest[1] terahertz (THz) wave oscillation ...

Optical injection locking is a technique by which the output of a semiconductor laser is stabilised and synchronised to that of an external “master” laser. This method harnesses the coherent ...

A team of international researchers has developed a new technique that promises to detect dark matter using atomic clocks and a network of optical-cavity lasers. An atomic clock is a super-precise ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...

Hold onto your hats, because computers could get 100,000 times faster if research led by the University of Michigan pans out. Using extremely short, configurable femtosecond pulses of light lasting ...

Physicists led by Johannes Roßnagel at the University of Mainz in Germany, the single atom engine is about as efficient as your car at transforming the changing temperature into mechanical energy.

erbium was used to make the very short pulses of light. Normal light is sent into one end of the erbium-enriched loop and interacts with the metal atoms to emerge as laser light from the other end." ...
