The fifth issue of lasers and photonics technologies is
published this February with the cooperation of the lasers, photonics and
micron structures technologies development headquarter.

According to the information center of national elites foundation, the lasers, photonics
and micron structures technologies development headquarter published the fifth
issue of lasers technologies with the cooperation of the knowledge-based
economy, technology and science development headquarter. This issue contains
five sections and is published in 84 pages.

According to this report, a note is presented in the first
section of the issue on the fact that science could shed light on the path of
life. The second section included speeches by Khanzadeh, head of the school of
basic sciences of Vali-E-Asr University of Rafsanjan, on research and
educational activities in the area of optics and photonics, students of
different educational levels, scientific events in school of physics in this
area, challenges and barriers of this field, position of Iran in this area, and
wealth creation.

Mansour Esfandiari Bayat, executive manager of the national
research technology project for laser leveling of agricultural land, explained
about the formation of this idea and its benefits and applications for farmers.

The third section included a report on the 11^th
congress on lasers in medicine of Iran and new laser ideas, which is presented
with the title of “neuroscience is brighter with light”. In addition, a report
on the second optogenetics workshop, which was held in Shahid Beheshti
University, is presented, which is introduced as a new field with a promising
future in the medical laser field.

The second section included vision, return to beauty with
golden wavelength and introduction of dyed lasers for treatment of skin
diseases. In addition, laser and extravagant colors, and Eli dyes and multi- multi-photorflow fluorescents that are
used in biological imaging are expressed.

New generation of wireless optical communications or
replacement of Wi-Fi cables with Li-Fi cables in establishment centers or
industrial applications are discussed in the third section, where gravitational
waves are evaluated with laser interferometer, which is one of the most
exciting results of Einstein's general theory of relativity.

The fifth section includes “knowledge to wealth”, where the
company of “Fath Nour Mihan” is introduced as one of the active companies in
the area of lasers and photonics. Moreover, one of the successful companies in
the area of lasers and photonics with the name of “Hamamateso” as the unknown
elite for knowledge and technology scholars has been discussed in this issue.

Laser news have been presented in the sixth section of this
issue, where the large event of west photonics, which is annually held in San
Francisco in one conference section or two workshop and exhibition sections, is
introduced.

In addition, finding a new light, which is a modern form of
light for research and fundamental applications, is presented in this section.

The seven section included the pioneers of this area, such
as Leon Goldman, who is one of the pioneers of this science. His activities and
achievements are introduced, and laser creation after primary studies and
preliminary theories is pointed out.

The eighth section included a book introduction for the
book of “applications of formation of laser beam”, which is used in various
areas. In addition, the Lumerical software is an accurate and safe tool for
simulation environments and showing the structure in various directions.

The final section of this special issue is allocated to the
technology school and light fraction, where some explanations are provided on cause
of light fracture, wave speed fluctuations, bending value, lenses and
refractive index of light.
