Investigation on physical properties of nanosized copper oxide (CuO) doped with cobalt (Co): A material for electronic device application
This study has reported about the preparation and characterization of Copper oxide (CuO) nanoparticles doped with Cobalt series at low temperature by Sol‐gel method. The characterization techniques like X‐ray diffraction (XRD), scanning electron microscope (SEM), Raman spectroscopy, defused reflectance spectroscopy (DRS), and DC measurement have been used to confirm its phase formation, that is, monoclinic, surface porous morphology, the redshift of Raman peaks confirms optical phonon confinement, whereas increasing bandgap signifies the quantum confinement effect. The semiconducting nature of samples has been observed by two probe method. Furthermore, the study has focused in detail on the effect of cobalt doping with varying concentrations by wt % on its structural, morphological, optical, and conductivity features. The paper describes the simple synthesis of CuO and doped CuO films for optoelectronic applications.

Battlefield Lasers and Opto-electronics Systems
During the last four decades or so, there has been an explosive growth in commercial, industrial, medical, scientific, technological, and above all, military usage of laser devices and systems. In fact, lasers have influenced every conceivable area of application during this period. While the expansion of non-military application spectrum of lasers is primarily driven by emergence of a large number of laser wavelengths followed by ever increasing power levels and reducing price tags at which those wavelengths could be generated, the military applications of lasers and related electro-optic devices have grown mainly because of technological maturity of the lasers that were born in the late 1960's and the early 1970's. Lasers have been used in various military applications since the early days of development that followed the invention of this magical device. There has been large scale proliferation of lasers and opto-electronic devices and systems for applications like range finding, target designation, target acquisition and tracking, precision guided munitions, etc. during 1970's and 1980's. These devices continue to improve in performance and find increased acceptance and usage in the contemporary battlefield scenario. Technological advances in optics, opto-electronics, and electronics, leading to more rugged, reliable, compact and efficient laser devices are largely responsible for making these indispensable in modern warfare. Past one decade or so has seen emergence of some new potential areas of usage. Some of these areas include rapid growth in the usage of lasers and opto-electronics devices and systems for electrooptic countermeasure (EOCM) applications, test and evaluation systems that can perform online functionality checks on military opto-electronics systems and also their interoperability. In this paper, an overview of the current and emerging military applications of lasers and opto-electronics systems has been given with an outline on the likely trends leading to performance enhancement of the existing systems and emergence of new application areas. Also, a brief on the developmental activity in the field of laser and opto-electronics devices and systems at Laser Science and Technology Centre (LASTEC), Delhi has been given.

Design and Development of Intracavity Optical Parametric Oscillator-based Eye Safe Laser Operating at 20 Hz without Forced Air Cooling
In this paper we report the design and development of an electro-optically Q-switched diode pumped Nd:YAG laser with intracavity optical parametric oscillator, generating ~ 5 ns laser pulses of ~8 mJ energy at eye safe wavelength of 1534 nm. A Z-shaped laser resonator has been designed with porro prism end reflector in Q-switch arm containing RTP Q-Switch and a suitably oriented waveplate. The gain arm consists of a Oe3 x 72 mm Nd: YAG laser rod, pumped from one side by 3 x 5 bar laser diode array stack emitting total optical peak power of 740 W at 804 nm at 38 degree C. Thermoelectric coolers (TECs) have been employed to maintain the optimum temperature of laser diode arrays and the combined heat load from the pump chamber and TECs is distributed over the system base plate with embedded heat pipes. Such cooling mechanism has eliminated the requirement of fins and fans in the laser system. Eye safe radiation is out-coupled through intra cavity KTA OPO (5 x 5 x 20 mm3) placed in the gain arm. Laser was operated at 20 Hz for several duty cycles of 10 min on and 10 min off and output energy remained stable within plus or minus 0.5 mJ without any forced air/liquid cooling.
