128-QAM Transmitter: The transmitter comprises of QAM sequence generator, M-ary pulse generator, CW Laser, Polarization splitter, LiNb Mach-Zehnder modulator and polarization combiner.
Two [micro]m CW laser is also known as thulium laser, which has a wavelength of 2013 nm and a penetration depth in tissue of 0.3 mm.

The mean power of CW laser used here was 30 W, spot diameter was 100 [micro]m, and spot velocity was 100 [micro]m/s.
A CW laser is generated by continuously pumping energy into the active medium to perform an equipoise between the number of atoms raised to the excited state and the number of photons emitted [10].
To the best of our knowledge, the evaluation of [[chi].sup.(3)] and optical power limiting of POA and PPy under CW laser has not been reported till date.
Geola has found that, using a pulsed laser with output at 440 nm (indigo/blue light), with test photoresist samples from Shipley and Micro Resist Technology, it can expose holographic pixels ('hogels') at a fifth of the exposure energy of a CW laser. It's variation of the direct write digital holography (DWDH) technique means requires a single hologram exposure to create a white-light viewable hologram, as the hogel records the calculated diffraction pattern of the H2 master (the white light viewable hologram).
In the DPP-assisted annealing, a Si p-n homojunction substrate is irradiated with CW laser light while applying a forward-bias current, to control the thermal diffusion rate of the B.
This figure also displays the other components used in the experiments, namely, a photoconductive switch made from a 2x1 mm intrinsic silicon die, a 2 W CW laser at 808 nm, and a fiber pigtail for coupling light from the CW laser to the photoconductive switch.
The optical pulses are obtained by modulating CW laser irradiation in MZM with previously mentioned bit sequence.
This bit error rate analysis is for short/medium transmission distance (<12Km).The dynamic noise for CW laser is 3dB.
