Details and Characteristics
Main features of the "LA series" of diffraction gratings.
1. 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.
2. The 'LA series' line up
Shimadzu Corporation has developed nine types of diffraction gratings covering laser wavelengths from the visible to near infra-red for a wide range of applications.
The diffraction gratings are replicas of high precision masters by using two light interference exposure and reactive ion-beam etching technology, thus ensuring a stable supply of gratings and excellent cost performance.
Furthermore, 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.
