Aston researchers use this to combine a high-power pump laser and the signals that they want to amplify, outputting higher power signals.
A fixed probe laser and a tunable, counter-propagating pump laser were focused inside a sample to generate the SBS signal.
In order to monitor the temporal profiles of the LIF and ASE from the 560 nm QD laser pumped by a 3rd harmonic (355 nm, 10 Hz) nanosecond laser, the output emission was transmitted to a UPD connected to an oscilloscope with the trigger signal being acquired from the Q switch out of the pump laser. In Figure 5, curve (i) shows the nearly smooth bell-shaped profile (temporal profile) of the pump pulse with FWHM of 10 ns, while curve (ii) illustrates the pulse shape of the threshold LIF, wherein the pulse width is only 3 ns, with a rise time of 1 ns and a fall time of 2 ns.
In view of the strong demand for coherent transmission products to support rising bandwidth demand for data center interconnect and metro networks, the Group leverages state-of-art design and manufacturing capability of 3SP Technologies ("3SP") and the TO-Can packaging technology of O-Net to make significant strides in pump laser technology as demonstrated by the development of the TO pump.
The probe laser is split in equal parts, one with pump laser interaction and the other without, thus serving as reference light.
For each sweep repetition, an array of prisms in SLIDER are activated by a synchronized pump laser that is patterned with a serrated illumination mask.
Existing Raman lasers typically use crystals of silicon, barium nitrate or metal tungstate to amplify light created by a pump laser.
Components including the pump laser, OPO and optional UM modules are mounted on a single, hermitically sealed optical bench, allowing the system to be moved without losing alignment.
In fiber Raman amplifiers, a strong pump laser provides gain to signals at longer wavelengths through stimulated Raman scattering within the optical transmission fiber.
Designed for applications such as dense wavelength division multiplexed (DWDM) fibre-optic telecommunications networks, the Metro EDWA unit integrates a pump laser, a pump multiplexer, a waveguide amplifier, a pump kill filter and a tap coupler in a 130 x 27 x 13 [mm.SUP.3] package.
