introduction

Among them, Desktop Small Picosecond laser technology is becoming an important tool in scientific research and industrial applications due to its unique advantages. This article will provide a detailed introduction to the principles, applications, and future development prospects of desktop femtosecond laser technology.

Technical principles

Desktop femtosecond laser technology is a laser technology that can achieve picosecond (1 picosecond=10 ^ -12 seconds) ultra short pulse output on desktop devices. The core of this technology lies in its ability to generate and maintain extremely short laser pulses, thereby releasing enormous energy in a very short period of time.

Mode locking technology: Desktop femtosecond lasers typically use mode locking technology to generate ultra short pulses. Mode locking technology introduces specific phase relationships into the laser cavity, allowing multiple frequency components of light waves to interfere with each other and form stable ultra short pulses.

Gain media: Commonly used gain media include titanium sapphire (Ti: Sapphire), ytterbium (Yb) doped crystals, or optical fibers. These materials can amplify ultra short pulses under the action of pump light.

Pulse compression technology: Through dispersion compensation and pulse compression technology, the pulse width can be further shortened to the femtosecond or picosecond level. Pulse compression techniques typically include methods such as Chirped Pulse Amplification (CPA) and Self Phase Modulation (SPM).
