What is a high power laser?

High-power lasers for instance used to be neodymium rod lasers that were pumped by discharge lamps, which emitted across an extremely large spectrum from NIR to UV into a solid angle of basically 4π, resulting in typical electrical-to-optical laser efficiencies of 2%–3% .

Could a monolithic laser array help terascale computing?

A wide range of applications from various fields requiring low-cost on-chip laser sources could benefit from this. In particular, for on-chip optical interconnects, the demonstrated monolithic laser array, together with the WDM technology, may finally pave the way to terascale computing.

Are YB lasers suitable for high-power operation?

Since we want to focus on power scaling and high-power operation, only Yb lasers are considered in the following. Today, mainly passive mode-locking techniques are used as they enable a shorter pulse duration than active mode-locking approaches, which are limited by the bandwidth of the electronics .

What is the output power of a laser?

The laser output power is over 100 mW at the bias current of above 370 mA. The far-field divergence angle of the laser was measured to be 25.5∘ 29.9∘ and the measured Lorentzian linewidth is 1.68 MHz at the bias current of 150 mA.

What is a strong signature of laser operation?

The clear discontinuity in the slope of the curve is another strong signature of laser operation. The laser threshold (Pth) was determined to be 22 ± 2.1 mW. When increasing the pump intensity to 3 Pth, a peak output power of 6.4 mW was measured, equivalent to an external efficiency of 6%.

How can a pre-ionizing laser 97 improve the stability of plasma?

Improving the stability of the plasma medium with a pre-ionizing laser 97, optimizing the experimental parameters and developing new injection and acceleration schemes (such as hybrid LWFA-driven PWFA 73, 74, 75) are methods that are being explored to facilitate the generation of reproducible high-quality electron beams.
