The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

In many industries, laser diffraction is used to perform routine particle size analysis. The power of laser diffraction is such that it has started to replace conventional techniques, such as sieving.

Laser diffraction needs a smaller representative sample when compared to sieving. However, it can also use larger samples. For a dry-dispersed laser diffraction experiment, the sample size ranges ...

Ultrashort laser pulses - that are shorter than a millionth of a millionth of a second -have transformed fundamental science, engineering and ...
