RESEARCH ON LASER. 2
Abstract.
The laser was first invented in early 1950 by Albert Einstein with the help of other
physicists and electrical engineers. The motive behind this invention was the search of
monochromatic radiation to study the spectra of molecules. Hetch (2010) claimed that Half a “
[2]
century has passed since Theodore Maiman's small ruby rod crossed the threshold of laser
emission. The breakthrough demonstration earned headlines, but in the early years, the laser
[2]
was called “a solution looking for a problem,” and there was a germ of truth in the joke” (p.
[2] [2]
1). Since then, there have been developments in the laser by scientists, physi sts, engineers, ci
and other personnel to improve its performance.
Additionally, these personnel have worked to increase the variety of lasers. Therefore,
[2]
through these advancements, lasers have proved their significant roles in scientific research,
consumer products, telecommunications, engineering, medicine, materials working, and other
applications. This paper reviews the highlights of these advances and puts them into
[2]
perspective by demonstrating how laser technology has grown to meet application
requirements.
Introduction.
Lasers are devices that emit collimated beams of intense light. These narrow beams
[0]
have the following properties; the laser light emitted is coherent. This means that the laser
light produced at the same time and in the same direction, unlike light waves, which are is
based on space and time. However, the laser light emitted is monochromatic. This implies
that the laser light produced is of the same wavelength, contrary to the light waves that are

that the laser light produced is of the same wavelength, contrary to the light waves that are
composed of different waves with different wavelengths.

Additionally, the light waves emitted by lasers are collimated. This means that they
are narrow, unlike the light waves which are divergent. Lastly, laser light h a high intensity as

LASER PROPERTIES
There are types of lasers, namely; Helium-Neon Laser, Argon, Krypton, and Xenon
Ion Lasers, Carbon Dioxide Laser, ND: YAG Laser, Excimer Lasers, Semiconductor Diode
Lasers, and Dye Laser. These laser types can be classified as gas lasers, solid lasers, and
liquid lasers (Waynant, 2001). Firstly, the excimer laser is used in micro-surgeries and

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Light Amplification by
Stimulated Emission of Radiation.
Optical electronic device that generates an
intense (very narrow) beam of
single color (monochromatic) light by
pumping (amplifying) photons with
more energy through collisions with other
photons. Laser beams can travel vast
distances without dispersion and can carry
enormous amounts of energy
(100 million watts per square centimeter, and
more).
Lasers are sources of light with a very special
properties.
6. Application of laser:
Laser are used in many various field.
MANUFACTURING (INDUSTRY)
MADICAL
METROLOGY
DATA-STORAGE
COMMUNICATIONS
DISPLAYS
SPECTROSCOPY
MICROSCOPY
ENERGY TECHNOLOGY
MILITARY
SCIENCE AND TECHNOLOGY
7.
8. Lasers are widely used in
manufacturing(industry), e.g. for cutting,
drilling, welding, cladding, soldering
(brazing), hardening, ablating, surface
treatment, marking, engraving,
micromachining, pulsed laser deposition,
lithography, alignment, etc.
9.
10. Use for the treatment of detached retinas.
Use in performing bloodless surgery
Use for the treatment of human and animal
cancers and skin tumtors.
11.
12. Optical fiber communication, extensively used particularly for
long-distance optical data transmission, mostly relies on laser
light in optical glassfibers. Free-space optical communications,
e.g. for inter-satellite communications, is based on higher-
power lasers, generating collimated laser beams which
propagate over large distances with small beam divergence
13.
14. Data Storage
Optical data storage e.g. in compact disks
(CDs), DVDs, Blu-ray Discs and magneto-
optical disks, nearly always relies on a laser
source, which has a high
spatial coherence and can thus be used to
address very tiny spots in the recording
medium, allowing a very high density data
storage. Another case is holography, where
the temporal coherence can also be important
16. In Lunar Laser Ranging Experiment, Laser
beams are focused through large
telescopes on Earth aimed toward the arrays,
and the time taken for the beam to be
reflected back to Earth measured to
determine the distance between the Earth and
Moon with high accuracy
17.
18. There are a variety of military laser applications. In
relatively few cases, lasers are used as weapons; the “laser
sword” has become popular in movies, but not in practice.
Some high-power lasers are currently developed for
potential use as directed energy weapons on the battle
field, or for destroying missiles, projectiles and mines.
In other cases, lasers function as target designators or
laser sights (essentially laser pointers emitting visible or
invisible laser beams), or as irritating or blinding (normally
not directly destroying) countermeasures e.g. against
heat-seeking anti-aircraft missiles. It is also possible to
blind soldiers temporarily or permanently with laser
beams, although the latter is forbidden by rules of war.
There are also many laser applications which are not
specific for military use, e.g. in areas such as range
finding, LIDAR, and optical communications.
