Question

Lasers emit light of a certain frequency in one, precise direction. The light that a laser emits can be tuned to have a high frequency and energy. Lasers that emit high-energy light are often used

Answer 1

Answer:

An ultra intense laser is one with which intensities greater than 1015 W cm-2 can be achieved.

Explanation:

This intensity, which was the upper limit of lasers until the invention of the Chirped Pulse Amplification, CPA technique, is the value around which nonlinear effects on the transport of radiation in materials begin to appear.

Currently, the most powerful lasers reach intensities of the order of 1021W cm-2 and powers of Petawatts, PW, in each pulse. This range of intensities has opened the door for lasers to a multitude of disciplines and scientific areas traditionally reserved for accelerators and nuclear reactors, applying as generators of high-energy electron, ion, neutron and photon beams, without the need for expensive infrastructure.

Answer 2

Answer:

b. as scalpels in surgical procedures.

Explanation:

Lasers are useful in clinicals for soft tissue surgery. It is used to cut, ablate, vaporize, and coagulate. There are several different laser wavelengths used in soft tissue surgery. Different laser wavelengths and device settings (such as pulse duration and power) produce different effects on the tissue.

It focuses a narrow beam and creates high-intensity light. This function; ability to focus very accurately on tiny areas, they can be used for very precise surgical work or for cutting through tissue (in place of a scalpel).
