Nd:YAG Laser Treatment

This educational kit is perfect for training users on the principles of operation of solid-state lasers, especially the Nd:YAG laser. In addition to hands-on activities and numerous measurements, the theory is extensively covered. This system is the most flexible on the market. All components can be installed and changed quickly, and many studies can be conducted according to your needs. This kit uses a 450 mW laser diode with integrated cooler and thermistor to control its temperature. The versatile electronic unit includes temperature control and injection current control of the laser diode, an integrated function generator to modulate the laser diode current, and an amplifier for the photodiode. Topics covered: - Properties of laser diodes, optical pumping by laser diode - Spectral properties of the active medium, fluorescence decay, and excited state lifetime - Assembly of a laser cavity and optimization of ouExperimentut power by aligning the resonator - Properties of transverse modes (TEM00 and more) - Criteria for stable laser operation and cavity optimization - Second harmonic generation by frequency doubling (KExperiment crystal) - Generation of short pulses by active Q-switch system (LiNbO3 crystal) or passive (Cr4+ : YAG saturable absorber) - Characterization of pulse generation: threshold, pulse shape, duration, and energy - Comparison of two active media Nd:YAG and Nd:YVO4 Principles and objectives: This educational kit allows for assembling, adjusting, and studying a diode-pumped Nd:YAG laser. Similar to Experiment 204834, the diode is first fully characterized, and the crystal absorption properties of Nd:YAG are investigated. The next step involves creating the resonator before studying its properties. Finally, the different options will allow for understanding frequency doubling or pulse generation.
