Optically pumped surface-emitting DFB GaInAsP/InP lasers with circular grating


Abstract

The lasing action in surface-emitting DFB lasers with circular grating (SE-CG DFB) is reported for the first time. 1.283 mu m laser oscillation is demonstrated by optical pumping. The threshold pumping power density is estimated to be 16.2 kW/cm2. The pulsed output power is more than 25 mW.


16.2 kW per sq cm is a lot of power. It would heat up anything including the atmosphere.

Atmosphere Above Japan Heated Rapidly Before M9 Earthquake

Infrared emissions above the epicenter increased dramatically in the days before the devastating earthquake in Japan, say scientists.

And they didn't warn.

This type of thing is not yet well-understood but it is hoped that it may one day lead to a warning system or possibly even an earthquake mitigation system. A phenomenon is being increasingly studied, called preseismic lithosphere-atmosphere-ionophere coupling.
