Abstract

We report successful compensation of the thermally induced laser beam distortion associated with high energy 110 mJ and high average power femtosecond laser system of 11 Watts operated with vacuum compressor gratings. To enhance laser-based light source brightness requires development of laser systems with higher energy and higher average power. Managing the high thermal loading on vacuum optical components is a key issue in the implementation of this approach. To our knowledge this is the first time that such thermal induced distortions on the vacuum compressor gratings are characterized and compensated.

Experimental set-up. The laser beam is represented by the red lines at 800 nm and by the turquoise lines at 400 nm. M, high reflectivity mirror; G, compressor gratings; CC, corner cube (beam elevator); DC, KDP doubling crystal. The compressor chamber can be isolated from the target chamber by a windowed gate valve (WGV) that allows the beam to propagate into the interaction chamber even if the latter is at air. OAP, off-axis parabola; TCC, target chamber center. The wavefront measurement system allows measuring the beam wavefront at 800 nm by using a leak at the back of a high reflectivity mirror: W, high transmission window; L1, f=+40 cm, aspheric lens; WFS, wave-front sensor. The imaging system allows to observe the focal spot at TCC with 45 times magnification: L2, biconvex f=+10 cm lens; MO, microscope objective; CCD, far-field monitor CCD.

Focal spot measured at the target center chamber position under vacuum for 400 nm, 110 mJ at the compressor entrance and 15 mJ incident at the target position. Each picture on this figure is taken for a different delay following insertion in the experimental setup and indicated below the picture number for a range from 5 up to 130 s.

Phase map of the laser beam. The phase map diameter corresponds to the entrance iris of the laser beam which is 21 mm for this measurement. a- Energy below 1 mJ at the compressor chamber entrance (no thermal loading). The RMS wavefront value is 0.061. b-Maximal energy of 110 mJ at the compressor entrance (thermal loading). The measurement is achieved after a delay higher than 100 sec. The RMS wavefront value is 0.081.

(a) Beam shape at the target center chamber after moving the off-axis parabola along the focal axis to compensate for the beam defocusing. This picture is taken with 110 mJ energy at the compressor entrance and for a delay higher than 100 s. Pictures from this figure and pictures set from Fig. 1 have been taken during the same set of measurement. (b) Best focus displacement as function of average power. The red line is a second order polynomial fit. (c) Laser pulse near field and corresponding cross sections. Gaussian fit is shown in red line.
