With organic laser diodes producing a much purer light than OLEDs--which makes them suited to a wider range of applications--to achieve the lasing
process, they require currents that are magnitudes higher than those used in OLEDs.
"We have been working to develop new lasing
media, using chemically synthesized quantum dots, although it had been widely believed that quantum dot lasing
with electrical stimulation is simply impossible.
'Kasi wala kayong ibang gawin pag lasing
na, pati army, wag kayong magdala ng baril.
The following parameters were measured and compared between the Regular and Moses modes: Procedure time as measured by the time from when the urologist started lasing
till stone was pulverized to dust.
But due to unique photoluminescence properties of QDs, which enable the design of photonic devices, other aspects of QDs have led to extensive research, because of the broadband spectral tunability, solution processability, low lasing
threshold, high-temperature operation, and impressive chemical stability offered by QDs [12-16].
In contrast to conventional lasers, where the feedback of the lasing
signal is provided by ordinary mirrors, this nanolaser utilises radiative coupling between silver nanoparticles.
Besides, the enhanced local field occurring in hot spots is particularly important to trigger low threshold lasing
resonance because it can locally enhance the pump rate of gain media [7,17],
These mechanisms include random lasing
[17-19], exciton-exciton P-band lasing
[20, 21], electron-hole plasma lasing
or N-band lasing
, nanosized or microsized whispering gallery mode dielectric resonators [23-26], coherent scattering of light by surface undulations , N-band lasing
enhanced by top-down microdisc structuring , and coherent reflection from self-assembled ZnO hexagons .
When the pump power attains 80 mW, some narrow peaks appear in a range from 391 nm to 398 nm on the broad UV band, which indicates a lasing
process occurring in the ZnO microrod.
In particular, it says its engineers have extensive experience of laser welding polymers which are widely used in the manufacture of balloon catheters and other medical device products The Synrad 48-1KWM Series lasers are said to be ideally suited for the lasing
of widely used materials such as Nylons, Pebax, PET and more, and catheter balloons ranging from 1mm to 20mm in diameters can be readily processed using a Synrad 48 series CO2 laser.
Although plasmon lasers have been demonstrated at different spectral ranges, from the ultraviolet to near-infrared, a systematic approach to manipulate the lasing
emission wavelength in real time has not been possible.
AS THE WEAPON BEGAN its freefall flight path towards my designation, my wingman began lasing
. He executed his role flawlessly.
