 Today we are introducing a brand new 532nm 5W solid-state laser. This laser now uses a touchscreen power supply. The power supply has a built-in cooling fan. This laser efficiently generates 532nm green light by frequency doubling the solid-state gain medium pumped by an infrared laser diode. Its core advantage lies in achieving high power output while maintaining excellent beam quality, low noise, and good stability—characteristics that make it outstanding in industrial and medical applications. Instructions for use: Turn on the power switch. The 'POWER' light will illuminate. After the machine starts, it will automatically jump to the current adjustment page. Here, we can adjust the current value to adjust the output power. Click the '+' and '-' buttons to the right of 'Current' to adjust the current. 1000 represents the full power current. The 'X 50' at the top represents an adjustment step of 50, and the 'X 1' in the second row repr...

Romanian scientists have developed a record-breaking 10 megawatt laser, which is equivalent to one-tenth of the energy produced by the sun on Earth. In addition to letting someone or something evaporate, it is mainly used for research purposes. Scientists from three countries will use this super-light laser to study photonuclear properties, cancer medicine, radiation research, and more. In 2014, the Extremetech website once described a 1 megawatt laser as the "Star of Death", and the laser developed today is ten times stronger. The laser was developed by the European Commission through an “ultra-light infrastructure” (ELI) project with an investment of 850 million euros. The project includes facilities in Romania, Hungary and the Czech Republic. The Romanian laboratory used it to study photonuclear physics. The Hungarian facility experimented with attosecond (1x10-18 seconds) laser pulses. The   group of the Czech   Republic studied short-pulse secondary sources and partic...

Realization of ultra short and super strong laser From the perspective of laser applications, the development of lasers is mainly to find higher power, shorter pulse width, and higher energy output. That is, the process of obtaining ultra-strong ultra-short laser pulses. The construction of ultra-short and  ultra-strong lasers  relies mainly on the development and innovation of laser amplification technology. Conventional lasers use Q-switching, mode-locking and other techniques to improve laser power output. To achieve laser output, it is first necessary to achieve particle inversion, and secondly to meet the energy gain greater than the loss. Q is the quality factor of the resonant cavity, which is used to measure the energy loss of the laser. The higher the Q value, the greater the optical loss of the resonant cavity. The corresponding laser threshold is higher. When the Q switch is in the off state, the inside of the cavity will accumulate more inverted particles at t...
