Wide-bandwidth mode-hop-free tuning of extended-cavity GaN diode lasers [PDF]

open access: yes, 2005
We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode ...

Volume Bragg grating external cavities for the passive phase locking of high-brightness diode laser arrays : theoretical and experimental study [PDF]

open access: yes, 2011
We describe the theoretical modeling of the external-cavity operation of a phase-locked array of diode lasers in two configurations, the self-imaging cavity based on the Talbot effect and the angular-filtering cavity. Complex filtering functions, such as

External cavity diode lasers and non-linear optical frequency conversion in spectroscopic applications [PDF]

open access: yes, 2006
Semiconductor diode lasers are successful tools in atomic spectroscopy. They are routinely used in frequency conversion applications to develop devices that access regions of the spectrum not directly available.

A liénard oscillator resonant tunnelling diode-laser diode hybrid integrated circuit: model and experiment [PDF]

open access: yes, 2008
We report on a hybrid optoelectronic integrated circuit based on a resonant tunnelling diode driving an optical communications laser diode. This circuit can act as a voltage controlled oscillator with optical and electrical outputs.

Method for calculating the use of nozzle hydrodiodes in design of two-tube hydraulic shock absorber [PDF]

open access: yesОмский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение", 2020
The development of a method for calculating the use of nozzle hydrodiodes in the design of a two-tube hydraulic shock absorber is carried out by considering such problems as the fragility and wear of movable elements (valves) in the design of a ...

Improving parameters of planar pulse diode using gettering

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2021
Pulse diodes are widely used as part of high-frequency pulse circuits. However, it should be noted that the cost of pulsed diodes remains relatively high, due to the low yield of suitable devices when they are sorted according to the criteria of reverse ...

A Solid State Pyranometer

open access: yesAnnals of West University of Timisoara: Physics, 2015
The construction of a solid state device-based pyranometer designated to broadband irradiance measurements is presented in this paper. The device is built on the physical basis that the temperature difference between two bodies of identical shape and ...

Comparison between radiochromic film and Sun nuclear edge diode detector during the commissioning of small field size radiosurgery cones

open access: yesBrazilian Journal of Radiation Sciences, 2022
Stereotactic Radiosurgery (SRS) is a procedure that uses ionizing radiation in a single fraction or few fractions to treat intracranial lesions. Usually, for these treatments, small photon fields, formed by circular collimators or micro multileaf ...
