<p><span>In this work; we present an enhancement in blue laser diodes with new factors and applications for modern technology such as underwater telecommunications, bio-sensor and bio-medical systems etc. Years of advance meanwhile have much enhanced laser performance, and extremely improved their diversity, making lasers significant parts in scientific research, telecommunications, engineering, bio-medical imaging, materials working, and a swarm of other applications. This article viewing how laser technology has progressed to chance application requirements. The enhanced blue laser building diagrams to get a peak efficiency% at room temperature with modification. Moreover, we have as well estimated electro-optical performance packing of blue laser diodes been significantly various associated to GaAs laser method and novel developments and performances are required to enhance the optical power from anther laser diodes. Researchers need enhanced approaches to accurately make new the blue laser applications to use control of modern experimental measurements and optical communication.</span></p>

Biosensors depend on cantilevers have developed a promising tool for detecting biomedical, optical laser communication and many fields of interactions with high accuracy. We modeled the operation of cantilevers with two magnetic and coil using Ansys program. This simulation technique can capably be used to select the appropriate design and dimensions of cantilever with the geometry of system. The primary main of the magnetic design is to improve the geometry of the coil and shape to yield a highly uniform for 3D of optical fiber includes Silica Glass and Nickel cantilever, two magnets and coil that apply to force on the cantilever cylinder is using as a cantilever in the designing of this case. Results from many assessments which usage micro-cantilever have made known that these biosensors can demonstrate good compassion and high resolve. Additionally, for smart materials will regulator the strategy in the associations of reducing the vibrations amplitude and frequency to development the effectiveness of the designer in the new uses. Purposes to this problem comprise modification the approaches of numbers the resonant frequency to yield by cantilivier after the signal pass from laser system. The experimental of mode resonant frequency (f n ) of 3933.1594 Hz illustrations reasonable agreement with the Comsol model being within 10% of the expected result.
