Page 4: Chapter 1 Warnings
Femtosecond Pulse Compressor Chapter 1: Warnings Warnings Chapter 1 Please observe the following precautions to ensure your safety and to avoid damaging the device. 1) This device requires the customer to perform optical alignment procedures. Please be cautious with the provided irises to avoid scratching the optics. -
Page 5: Chapter 2 Safety
Chapter 2: Safety Safety Chapter 2 When operating the Femtosecond Pulse Compressor (Item # FSPC), please observe all necessary precautions for working with laser light, including, but not limited to, the following: Always use appropriate laser safety eyewear. Always inspect your eyewear for scratches and other damage before use. -
Page 6: Chapter 3 Description
The positive dispersion that is applied by the optical system acts to cancel out the negative dispersion applied by the FSPC, thereby minimizing the pulse width at the sample and maximizing image contrast. Precompensated beams can also use a lower average power to obtain the same image quality as uncompensated beams, resulting in less photobleaching. -

Positions in the diagram that are not circled are used by Thorlabs during assembly. 4.2.2. Riser Plate The FSPC is designed for a standard beam height of 4.25" (108 mm). This is nearly the same height as that used by Mai Tai ®... -
Page 8: Optical Alignment Procedure
Optical Alignment Procedure The input of the FSPC is on the right side of the housing, above the battery door. The output is on the front side. 1. Insert the two irises into the iris positions of the input beam path (positions A1 and A2 in Figure 2). -
Page 9: Insertion Calibration And Dispersion Lookup
Femtosecond Pulse Compressor Chapter 4: Setup 4.4. Insertion Calibration and Dispersion Lookup The external LCD panel displays the insertion of the large prism in the beam path. This is not a direct measure of the dispersion of the unit, as a given insertion will result in different dispersion values for different wavelengths. In order to know the dispersion of the unit, the user will need to consult the dispersion plot (Figure 7). -
Page 10: Chapter 5 Operation
The knob shown in the photo above changes the value of the negative dispersion by controlling the large prism insertion. Turning the dial clockwise makes the dispersion provided by the FSPC more positive, while turning it counterclockwise makes the dispersion more negative. In general, the knob should be rotated clockwise if there are few dispersion-adding optics after the FSPC, and it should be rotated counterclockwise if there are many dispersion-adding optics after the FSPC. -
Page 11: Dc Voltage Output
Audio Jack for Prism Insertion Readout and Battery Door The side of the FSPC contains a female 3.5 mm audio jack which outputs a DC voltage signal for automated readout of the measured prism insertion. The prism leadscrew has a pitch of 0.1" (~0.254 mm). -
