Recent Laser Innovations – RLD2WMUV2

laser-diodeLaser – a very useful technology – is a device that emits electromagnetic radiation through stimulated emission. As per the popular literature laser light is usually spatially coherent, which means that the light either is emitted in a narrow, low-divergence beam, or can be converted into one with the help of optical components such as lenses. Typically, lasers are thought of as emitting light with a narrow wavelength spectrum. This is not true of all lasers, however: some emit light with a broad spectrum, while others emit light at multiple distinct wavelengths simultaneously. The coherence of typical laser emission is distinctive. Most other light sources emit incoherent light, which has a phase that varies randomly with time and position.

Laser has come a long way since 1917 when Albert Einstein laid down the foundation for the invention of the laser and its predecessor, in his paper On the Quantum Theory of Radiation. It is being used in so many industries as well as medical processes.

ROHM Semiconductor offers RLD2WMUV2 – single mode dual wavelength laser diode features excellent low current characteristics making it ideal for DVD players. The RLD2WMUV2 utilizes original monolithic technology in order to deliver low threshold current capability and excellent temperature characteristics. In addition, it can be combined with ROHM’s high frequency modulation IC for significantly reduced noise. All ROHM products are both lead-free and RoHS compliant.
