Abstract

Krmiljenje pulznih laserjev zahteva krmiljenje in upravljanje številnih parametrov, ki so direktno povezani z laserskimi pulzi, kot na primer čas začetka laserskega pulza, čas njegovega trajanja, število pulzov in način delovanja. Od krmilnikov se zato običajno zahteva visoka časovna ločljivost in točnost pri generiranju krmilnih signalov. Magistrska naloga obravnava raziskavo možnosti uporabe 32-bitnega mikrokrmilnika za generiranje krmilnih signalov in opredeli njegove omejitve. Predstavljeni so v okviru naloge zasnovani in raziskani podporni elementi krmilnika, kot je namensko tiskano vezje in grafični uporabniški vmesnik. Naloga se osredotoča na generiranje signalov s frekvencami višjimi od 1 MHz. Časi trajanja posameznih pulzov in oblika signalov so bili preverjeni z osciloskopom. Krmilnik je bil preizkušen na dveh različnih krmilnih modulih za vzbujevalne laserske diode, pri čemer so bile uporabljene ponavljalne frekvence v območju med 1 MHz in 32 MHz.

Secondary title:	Driving and control of a pulse laser with a microcontroller
Secondary abstract:	Driving of pulsed lasers requires management and control of numerous parameters directly related to the laser pulses, such as the start time of the laser pulse, its duration, the number of pulses, and the operating mode. Therefore, controllers are typically required to have high temporal resolution and accuracy in generating control signals. This master's thesis examines the possibilities of using a 32-bit microcontroller for generating control signals and identifies its limitations. The supporting elements of the controller are explored and designed within the scope of the thesis, such as a dedicated printed circuit board and a graphical user interface. The thesis focuses on generating signals with repetition rates higher than 1 MHz. The duration of individual pulses and the shape of the control signals have been observed using an oscilloscope. The proposed controller has been tested on two different drivers for seed laser diodes, with signal frequencies ranging from 1 MHz to 32 MHz.
