Measuring laser power is a challenge. We can concentrate the lasaer pointer energy on a sensor and measure the resulting temperature rise, or measure the power of a given portion of the beam. For the first option, the laser must be switched from its normal propagation path, so it cannot be used in production. Between…

The researchers achieved real-time measurements of laser power in a high kilowatt range
Measuring lasaer pointer power is a challenge. We can concentrate the laser energy on a sensor and measure the resulting temperature rise, or measure the power of a given portion of the beam. For the first option, the laser must be switched from its normal propagation path, so it cannot be used in production. Between…
European scientists have used microresonators to create the world’s smallest optical frequency comb
According to McCombs, an optical frequency comb (OFC) is a laser source whose spectrum consists of a series of discrete, uniformly spaced comb lines that can be used for precise measurements. Over the past two decades, they have become major tools in applications such as precision ranging, spectroscopy and communications. Most based on mode-locked lasaer…
Researchers used a powerful laser to boost the energy of pulses in terahertz to set a new world record
Li yutong, L05 group, key laboratory of optical physics, institute of physics, Chinese academy of sciences/national research center for condensed matter physics, Beijing, and a research team composed of zhang jie, academician, Shanghai jiaotong university, liao guoqian and others, explored a new way of terahertz radiation generated by intense lasaer pointer-solid target interaction. Based on…
HiLight laser automatic extinction ratio control technology has been patented in USA
HiLight Semiconductor recently announced that it has received a us patent for its self-developed lasaer pointer auto-extinction ratio control technology. The patent, U.S. patent no. 10,205,532, is a so-called “double-loop” transmitter control feedback loop designed specifically for the cost-sensitive and high-volume FTTH optical communications market. It can control output power and modulation amplitude of transmitter…
Progress has been made in organic panchromatic laser displays
Laser display technology is the fourth generation of display technology after black and white display, color display, digital display, with panchromatic range, high brightness, extreme hd, true 3D and other subversive advantages. However, the use of projected tri-colour lasaer pointer has limited the use of laser displays in tablet applications such as mobile phones. It…
Scientists use ultrafast laser pulses to weld metal and glass
This week, scientists at heriot-watt University claimed to have used a groundbreaking method that USES ultra-fast lasaer pointer pulses to weld together materials such as glass and metal. Traditionally, welding has been limited to materials with similar properties. At present, equipment and products involving glass and metal are usually held together by adhesives, which are…
The researchers used terahertz radiation to determine the boundaries of brain tumors
According to mmes consulting, a team of scientists from Moscow state baumann technical university, boldenko institute of neurosurgery and prokhorov institute of basic physics, Russian academy of lasaer pointer sciences, have proposed a method to determine the boundary of brain tumors using terahertz radiation, thus significantly improving the effect of treating brain tumors. Gliomas, the most…
How to choose laser trackless navigation
In recent years, mobile robot technology has been greatly developed in the world, and the navigation technology of robot has also been developed rapidly, from the former magnetic stripe navigation, two-dimensional code navigation, to the popular laser trackless navigation. For lasaer pointer trackless navigation which does not need to lay magnetic stripes on the ground,…
Us department of defense: laser weapons have advantages in dealing with swarm drones
The us department of defense believes that lasaer pointer weapons are highly accurate, responsive, fast and virtually immune to gravity, giving them an edge in dealing with threats such as swarm drones, rockets and artillery shells. According to the us department of defense, laser weapons are ideal for destroying small, fast targets such as incoming…
