“…In 1996, Nakamura and co-workers [1,2] introduced the first demonstration of a room-temperature nitride-based CW blue laser. Nowadays, GaN-based laser diodes have wide range of applications in electronics [3], sensing [4,5], military and defense [6][7][8], telecommunications [9], optical lithography [10], medical treatment [11], trace gas detection [12,13] and many other fields of research in modern science and technology [14].…”

“…For the purposes of this study it was necessary to design and build custom equipment which had to meet certain requirements such as easy handling, reproducibility of the results in controlled environment and simple interface for setting input parameters before each new study. Similar assembly designs for laser diode output control were found in [11,12]. Light excitation of CQD is provided using violet laser light.…”

Construction and characterization of a simple but flexible, low cost diode laser system for the excitation of carbon quantum dots as a treatment method for ocular cancers is reported. System was designed to deliver maximal amount of laser diode radiant flux to the eye of the test mice using optical cable. Detailed electronic circuit layouts of the laser diode voltage controller, supplying maximum 3 V of voltage with 20 mV resolutions, and functional description of all other components (optical cable delivery system and supporting console) are given. The system features visual signalization when the laser diode module is powered. Since the laser diode radiant flux is directly dependent on the input voltage, measurement was performed in order to obtain approximation function of this dependency. Purpose of this function is to eliminate radiant flux measurement before each experiment which requires controlled conditions Keywords -carbon quantum dots, laser excitation, laser diode assembly, voltage control, radiant flux or e Klisi is with the

“…CO 2 lasers have high power, so they allow high production speeds and material cutting (Martinez-Conde et al 2017). However, they generate longer wavelengths (10,600 nm), so they are not as accurate as the diode layers of a visible spectrum (455 nm) (Rothenbach and Gupta 2012). The use of semiconductor lasers has experienced a huge increase with the use of CD drives (Barletta et al 2007;Hernández-Castañeda et al 2011).…”

Laser engraving of photographs on wood surfaces is a challenging task. To optimize the outcome and production quality it is necessary to control every aspect of the laser engraving process. Most of the production machines and technologies overall are mainly focused on laser power control. However, with other systems and deeper knowledge of the wood characteristics it is possible to achieve even better quality. This paper deals with enlarging the number of achievable shades of burned wood and its optimization. A calibration system was developed to control colour shades of engraved wood with a combination of laser power and optic focus. With this approach it is possible to widen achievable palette of engraved shades by continuous control of chemical processes of laser and wood interaction. The production is divided into wood burning and wood carbonization by variation of laser beam focus.
