Pulsed fiber lasers, with their excellent beam quality, reliability, the longest maintenance-free time, the highest overall electro-optical conversion efficiency, pulse repetition rate, smallest volume, the simplest and most flexible usage method without water cooling, and the lowest operating costs, have become the only choice for high-speed and high-precision laser marking.
The characteristics of pulsed fiber lasers
Excellent beam quality
The quality of the beam is directly related to the improvement of work efficiency and the optimization of space utilization.
High quality fiber output
The output quality of fiber lasers is mainly measured by beam quality parameters (such as M² factor, BPP value) and power stability and other indicators.
High Power Stability
Short-pulse (nanosecond, picosecond level) lasers have higher stability requirements due to their concentrated energy.
quick switching response
The Q-switch is an important optical component in a laser optical system. It suppresses and generates laser pulses by blocking and not blocking the reflection channel of light.
Maintenance free operation
The integration and product features of the laser require a relatively low labor cost for maintenance.
High wall plug efficiency
High plug efficiency is an important indicator for measuring the efficiency of a laser in converting input electrical energy into output light energy . The higher the value, the smaller the energy loss.
Convenient control interface
The simple and convenient control interface can improve work efficiency.
High frequency modulation
Modulation frequency refers to the highest electrical signal frequency that a laser can respond to, which directly affects data transmission rate, detection accuracy, etc
The applications of pulsed fiber lasers
SINO GALVO W Series 30w Q-switched Pulsed Fiber Lasers
The Q-switched pulsed lasers of the Sino Galvo W series have excellent beam quality, adjustable repetition frequency, and the heat dissipation design of the product can meet the working environment of 0-40℃, supporting 24 hours and 7 days.
The above continuous and stable operation. Meanwhile, this product is equipped with the latest generation of variable-frequency cooling fans, based on the internal core.
The fan speed can be adjusted in real time according to the component temperature, taking into account both heat dissipation and noise reduction. In terms of compatibility, it supports DB25 pass.
Use the control interface to match mainstream laser control software.
What is a Q-switched lasers?
Q-switched lasers (Q-switched lasers) are devices that achieve high-energy pulsed laser output by adjusting the quality factor (Q value) of the optical resonant cavity. Their core principle is to compress continuous or pulsed laser energy into pulses with an extremely narrow time width, thereby significantly increasing peak power.
