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, ...

Laser tuning gratings are holographic gratings specially designed for wavelength tuning of lasers, such as dye lasers, Ti-sapphire, or external cavity diode lasers. The groove depth is optimised to ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

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

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...
