Jenoptik´s Optical Systems division at LASER 2009:
new developments in microoptics, optoelectronics systems and digital imaging

At „LASER World of Photonics“ from June 15 to 18, 2009 in Munich, the world´s leading trade fair for optical technologies, Jenoptik´s Optical Systems division will present numerous innovative products in hall C2 at booth #311.

Pulse Compression Gratings (PCGs) with outstanding thermal stability for Ultrashort-Pulse-Lasers

JENOPTIK Businesss Unit Microoptics, a world leader in microoptics, provides two product lines of Pulse Compression Gratings for the utilization in Femtosecond–Lasers. Diffraction gratings are a key element for pulse compression of laser systems. In addition to our high performance transmission
gratings we have developed highly efficient dielectric reflection gratings to cover the whole application area for customers from Ophthalmology to Laser Materials Processing.
State of the art gold coated reflection gratings suffer from poor performance in terms of efficiency and absorption. The new dielectric reflection Pulse Compression Gratings, designed for 1030 nm and 1057 nm wavelength with a groove density of 1740 lines per mm, enable very compact setups
due to the feasibility of small areas for higher power due to low absorption.
The dielectric reflection PCGs show efficiencies of more than
97 %. The new product complements the existing product line of transmission PCGs with high damage threshold and outstanding thermal stability.
