Lasers
Laser fundamentals, safety, and types organized by temporal mode — from CW through pulsed to ultrafast — plus beam characterization.
Laser Fundamentals
Core laser principles — stimulated emission, gain media, resonators, bandwidth, coherence, modes, EM regions, key parameters.
Laser Safety
Laser classification, hazard evaluation, protective equipment, and controlled area requirements. Essential knowledge for anyone working with lasers.
CW Lasers
Continuous-wave types — gas, DPSS, fiber, diode, tunable. Parameters, advantages, and application matching.
Pulsed Lasers
Pulsed operation — Q-switching, gain-switching, cavity dumping. Pulse parameters, peak power, ns/µs regime applications.
Ultrafast Lasers
Femtosecond and picosecond systems — mode-locking, CPA, dispersion management, ultrafast-specific optics.
Beam Characterization
Beam profiling, quality metrics, spatial profiles, M², waist measurement, pointing stability, power/energy measurement.
