Planar diffraction gratings

Shimadzu

Shimadzu Corporation introduces new customizable 'LA series' of planar diffraction gratings for laser systems. Diffraction grating elements for 633 nm to 1064 nm waveband with 1600 lines/mm, exhibit a diffraction efficiency of 98% - the highest in this category of technology. This feature is important for expansion and compression of laser pulses for light sources used in laser processing. The gratings can also be used in analytical instruments for research in life sciences, chemistry, environmental monitoring, and optical communications.

Shimadzu Corporation will produce customized gratings in accordance to customer requests for specific coating properties, and substrate and external shapes, for the production of gratings with the desired, highly specific characteristics.

The 'LA series' of diffraction gratings feature high diffraction efficiency over a wide wavelength range. The groove shapes are designed to attain the highest efficiency for TM polarized light for each laser wavelength band. These device characteristics are particularly suitable for external resonators and cavities, and pulse control.

In particular, diffraction grating elements for 633 nm to 1064 nm waveband with 1600 lines/mm, exhibit a diffraction efficiency of 98% - the highest in this category of technology. This feature is important for expansion and compression of laser pulses for light sources used in laser processing.

The 'LA series' diffraction gratings will be exhibited at SPIE Photonics West 4-6 February, 2014 at the The Moscone Center in San Francisco (USA).
