UV Dazzler for direct shaping of UV femtosecond laser pulse

								Conventional pulse shaping systems for operation in the Near Infrared Range (NIR) often use modulators (Liquid Crystal, deformable mirror or acousto optic modulator) that are placed in the Fourier plane of a 4f zero dispersion optical delay line. Liquid Crystal modulators however are not transparent in the UV wavelength range, deformable mirrors are phase only modulators, and acousto-optic modulators featuring a transverse interaction between the acoustic and light waves suffer from poor diffraction efficiencies when operating over wide bandwidths. Besides being bulky and sensitive to both alignment and thermal environment, these 4f zero dispersion optical delay line set up often require drastic calibration procedures for accurate operations.
........NEW!!!.......
								Fastlite recently introduced a new Dazzler system based on KDP material. This UV Dazzler presents all the advantages of the Dazzler systems compared with conventional pulse shaping systems, such as: No need for extra optical components, no complex alignment procedures required,in line geometry thanks to its patented longitudinal acousto-optic interaction. No need for calibration: the shaping is as accurate as we know the material characteristics of the crystal. Ultracompact device: the acousto-optic device is as small as 100mm * 50mm. You do not need any other optical component on your optical layout! High throughput efficiency: the diffraction efficiency of the UV Dazzler is typically 20% for a 30fsec input pulse duration in the UV
