Abstract:
Abstract: Nowadays, almost all of them use a dispenser, because of its practicality. But behind that there are several things that make the dispenser less efficient when taking drinking water from the glass, because the user has to press or turn the water tap in the dispenser. The working system of this tool is where the machine will run according to the commands obtained from the laser diode and the LDR sensor, the laser diode will reflect light that leads to the LDR. when the light reflected by the laser diode to the LDR is cut, it can be interpreted that the LDR and the laser diode detect or read the presence of an object in the form of a glass, automatically the two sensors instruct the controller to activate the water pump and the water pump will work to remove the water which will be filled in the glass that is placed in the dispenser with the volume of the glass used, the filling process and the end of filling will be displayed by the LCD and when filling the water the glass is full there will be a warning from the buzzer in the form of a sound. Users no longer need to press or turn the water tap when taking water from the dispenser using a glass.

Namun dibalik itu semua ada beberapa hal yang membuat dispenser kurang efisien saat mengambil air minum pada gelas, karena pengguna harus menekan atau memutar keran air yang ada pada dispenser. Sistem kerja dari alat ini ialah dimana mesin akan berjalan sesuai dengan perintah yang didapat dari Dioda laser dan sensor LDR, Dioda laser akan memantulkan cahaya yang mengarah pada LDR, pada saat cahaya yang dipantulkan Dioda laser ke LDR terpotong maka dapat diartikan LDR dan Dioda laser mendeteksi atau membaca adanya benda berupa gelas, secara otomatis kedua sensor tersebut memerintahkan controller mengaktifkan pompa air dan pompa air akan bekerja mengeluarkan air yang akan diisikan pada gelas yang diletakkan pada dispenser dengan volume gelas yang digunakan, proses pengisian dan akhir pengisian akan ditampilkan oleh LCD dan saat pengisian air pada gelas penuh akan ada peringatan dari buzzer berupa bunyi. Pengguna tidak perlu lagi menekan atau memutar keran air saat mengambil air pada dispenser menggunakan gelas. Kata Kunci : Dispenser;Sensor LDR;Dioda Laser dan Alat

Abstract:
The 1.55 μm waveband integrated external cavity tunable diode lasers have excellent merits such as their small volume, low cost, low power consumption, wide tuning range, narrow linewidth, large side mode suppression ratio, and high output power. These merits have attracted many applications for the lasers, such as in wavelength division multiplexing, passive optical networks, mobile backhaul, and spectral sensing technology. In this paper, firstly, the basic structure and principle of integrated external cavity tunable diode lasers are introduced, and then two main integrated structures of 1.55 μm waveband external cavity tunable diode lasers are reviewed and compared in detail, namely the hybrid integrated structure and monolithic integrated structure of 1.55 μm waveband integrated external cavity tunable diode lasers. Finally, the research progress in 1.55 μm waveband integrated external cavity tunable diode lasers in the last decade are summarised, and the advantages and disadvantages of 1.55 μm waveband integrated external cavity tunable diode lasers are analysed. The results show that, with the transformation of optical communication into more complex modulation formats, it is necessary to integrate miniature 1.55 μm waveband external cavity tunable diode lasers. Low-cost integrated 1.55 μm waveband external cavity tunable diode lasers are expected to be used in the next generation of optical transceivers in small-factor modules.

Abstract:
Hot-wall epitaxy (HWE) has been used to grow heterostructure lead-salt materials from which low-threshold tunable diode lasers have been made. A new HWE structure consisting of a Pb(Se, Te) layer sandwiched between two lattice-matched (Pb, Sn)Te layers has resulted in lasers of good electrical and material quality, and threshold current densities as low as 200 A∙cm−2 (at 40 K). This occurred even though this structure is expected to be nonconfining to both light and electrical carriers. This result is due to the very rapid interdiffusion of dopant atoms between the epilayers during the growth process. Dopant interdiffusion has been investigated using an etch-back technique combined with hot-point probe measurements to observe changes in the doping profiles of the structures. Very large values for the diffusion constants of dopants have been deduced from these measurements: 2.3 × 10−15 and 1.1 × 10−15 cm2∙s−1 for Bi and Tl, respectively.

Abstract:
Only a few reports exist on the treatment of therapy-resistant inflammatory glaucoma with contact transscleral cyclophotocoagulation (CPC), and only one in which the red 647nm krypton or 670nm diode lasers are used. The lasers most frequently employed in clinical practice are the 810nm diode and the 1,064nm neodynium:yttrium–aluminium–garnet (Nd:YAG) lasers. Although transmission through the sclera is lower with the red 647nm krypton and 670nm diode lasers than with the infrared 810nm diode and Nd:YAG lasers, this is compensated for by using contact application and compressing the sclera with the probe. Also, the red lasers have a higher affinity for the pigment epithelium of the pars plicata. Transscleral red laser CPC has proved to be an effective, simple and well tolerated procedure for the treatment of therapy-resistant inflammatory glaucoma, particularly in adults.

The design of room-temperature, InGaAsSb/AlGaAsSb diode lasers has evolved from the first double-heterojunction lasers described in 1980 that operated in the pulsed-current mode to present-day continuous–wave (CW), high-power, quantum–well diode lasers. We discuss in detail recent results from type-I-heterostructure, GaSb-based CW room-temperature diode lasers. The devices operate within the wavelength range of 1.8 to 2.7 μm, providing output powers up to several Watts. We analyze the factors limiting device performance.

Abstract:
Abstract Semiconductors lasers from several manufacturers have been investigated. Rate equations were proposed to describe the dynamics and explain the mechanisms of the appearance of quantum noise in diode lasers. Stationary solutions of the rate equations were obtained. For the lasers under study, the threshold currents and the number of photons at the threshold are obtained. Four mechanisms of the quantum noises appearance were described: Poisson noises of the photons, Poisson noises of the electrons, shot noises of the pump current, and quantum noise of the radiation field. The photon lifetimes for the investigated diode lasers have been determined. The shot noise of the pumping current does not play a significant role. The Poisson noise of photons is responsible for the maximum noise at the generation threshold of a diode laser. The analysis of quantum noises of quantum-cascade diode lasers is carried out.
