Burst Mode Lasers: Understanding the Technology

Introduction

Burst mode lasers are a type of pulsed lasers that operate by emitting bursts or groups of pulses. This technology offers flexibility in controlling pulse parameters and finding applications in various fields such as laser material processing and high-speed imaging.

Characteristics of Burst Mode Lasers

Burst mode lasers can be characterized by parameters such as pulse energy, duration, peak power, and pulse repetition rates within bursts. Each burst consists of a specific number of pulses, and bursts can be repeated at fixed intervals or triggered on demand.

Applications of Burst Mode Lasers

Burst mode lasers find applications in laser material processing, high-speed imaging, distance measurements, optical fiber communications, and laser-induced plasma ignition in combustion engines. These lasers are tailored to meet the specific requirements of each application.

Types of Burst Mode Lasers

Burst mode lasers can be realized using various technologies, including Q-switched lasers, mode-locked lasers with pulse pickers and amplifiers, mode-locked lasers with pulse splitters, seed laser diodes with amplifiers, and microchip lasers. Each type offers different capabilities in terms of pulse energy, duration, and repetition rates.

Frequency Conversion

Due to their high peak power, burst mode lasers can be equipped with devices for nonlinear frequency conversion, such as frequency doublers or optical parametric oscillators. This allows for the generation of laser light at different wavelengths for specific applications.

Conclusion

Burst mode lasers represent a versatile technology with a wide range of applications across various industries. Understanding the characteristics and types of burst mode lasers is essential for utilizing their capabilities effectively in different fields.
