Lasers

Laser fundamentals, safety, and types organized by temporal mode — from CW through pulsed to ultrafast — plus beam characterization.

8 topics

Laser Fundamentals

live

Core laser principles — stimulated emission, gain media, resonators, bandwidth, coherence, modes, EM regions, key parameters.

Laser Safety

live

Laser classification, hazard evaluation, protective equipment, and controlled area requirements. Essential knowledge for anyone working with lasers.

CW Lasers

live

Continuous-wave types — gas, DPSS, fiber, diode, tunable. Parameters, advantages, and application matching.

Pulsed Lasers

live

Pulsed operation — Q-switching, gain-switching, cavity dumping. Pulse parameters, peak power, ns/µs regime applications.

Ultrafast Lasers

live

Femtosecond and picosecond systems — mode-locking, CPA, dispersion management, ultrafast-specific optics.

Beam Characterization

live

Beam profiling, quality metrics, spatial profiles, M², waist measurement, pointing stability, power/energy measurement.

Nonlinear Optics

live

Second-harmonic generation, optical parametric oscillators, phase matching, and frequency conversion techniques for laser systems.

Laser Amplification

live

MOPA architectures, regenerative and multi-pass amplifiers, gain saturation, ASE management, and chirped pulse amplification.
