A switchable and tunable dual-wavelength single-longitudinal-mode (SLM) fiber laser in a 2-μm region based on saturable absorber and self-injection locking is proposed and experimentally demonstrated.

The LLSAW in lithium niobate on stress-free surface reveals rather high attenuation of the order of one dB per wavelength. Calculated resonant characteristics of a long IDT and dispersion curves of ...

1pm: The Wave’s PR team responds to Wavelength, releasing a press statement that a new company has now taken over ownership of the business and that new CEO Julian Topham is in place to lead it ...

However, none of the particles are transported along a longitudinal wave. Instead, they move backwards and forwards between compressions as the wave is transmitted through the medium .

In this paper, using the Bernoulli sub-equation function method, we obtain new dark, complex and singular soliton solutions for the longitudinal wave equation in a magneto-electro-elastic circular rod ...

The founder of The Wave in Bristol has taken to Instagram this evening, releasing a video describing the past few days as ‘a storm’. Nick Hounsfield founded the world’s first public Wavegarden Cove in ...
