HP100A-50KW-GD laser power detector for measuring extremely high power laser beams

The beam emitted by almost all laser systems follows the Angle pattern of Gaussian distribution. The Gaussian irradiance distribution means that irradiance has a smooth peak at the center point and slowly declines toward the edge. In theory, the irradiance level of a Gaussian distribution can never reach zero, which means that the distribution can expand indefinitely. This phenomenon in the laser ...

High brightness semiconductor lasers have extremely important applications in fields such as laser radar. Traditional semiconductor lasers face challenges such as large vertical divergence angle, elliptical beam output, multiple lateral modes, and poor beam quality, which limit the direct application of high brightness semiconductor lasers.In response to this challenge, the team from the Bimberg S...

The formation of dissipative solitons is influenced by various factors, such as spectral filtering effect and Kerr nonlinearity effect. This interaction leads to the possibility of mode locking on a large range of parameters, generating pulses with completely different types and evolution from conventional physical laws and optical properties, tolerating higher nonlinear effects, and effectively a...

The new architecture based on metamaterials provides a promising platform for constructing large-scale production and reprogrammable solutions that can perform computational tasks using light.The idea of simulating computers - a device that uses continuous variables instead of zero sum ones - may evoke outdated machinery, from mechanical watches to bomb sight devices used in World War II. But emer...

Laser is considered a sharp sword that cuts iron like mud, but even sharper swords can have tricky moments. For example, in certain scenarios, there are materials with higher reflectivity, such as silver, copper, etc., known as "high reflection materials". High reflective materials have a low absorption rate for lasers, making them difficult to process and potentially causing equipment failure or ...
