Description
Atomfair-LaserLab386 Semiconductor-Pumped Laser Principle Experiment Setup
Product Overview
Atomfair-LaserLab386 is a high-performance experimental device belonging to the optoelectronics and laser category, specifically designed for nonlinear optics experiments in college modern physics teaching. Launched in July 2022, this setup takes an 808nm semiconductor-pumped Nd:YVO₄ laser as its core research subject, enabling students to engage in hands-on operation and in-depth exploration of laser principles and technologies.
With a scientific and reasonable configuration, the device supports students in adjusting laser optical paths independently. By inserting a KTP crystal into the resonant cavity, it can generate 532nm frequency-doubled light, allowing for intuitive observation of frequency doubling phenomena and accurate measurement of key parameters such as phase matching angle and threshold. It serves as an indispensable practical tool for students to master core knowledge of laser principles and related technologies.
Key Experimental Projects Supported
- Measurement of the working principle and photoelectric characteristics of semiconductor lasers
- Working principle, installation, and commissioning of semiconductor-pumped solid-state lasers
- Basic principles of solid-state laser frequency doubling and laser frequency doubling phase matching angle selection experiments
