Installing The MOPO-700Conimls and indicatorsAll status indicators and controls for the MOPO-710 are located on the ElectronicsControl Unit.Installation of the MOPO-710When following the procedures below, always operate the pump laser at lowlevels to prevent optical damage to the MOPO-710. For pumping with the thirdharmonic, this would be oscillator only, un-a-switched. about 1-2 incrementsabove threshold on the lamp energy adjustment.Place the MOPO-710 in the appropriate position on the table, relative tothe pump laser, as shown in figure 3-6.Select the long-pulse mode of operation of the GCR pump laser, and slowlyincrease the lamp joules until a small amount of green, 532nm light is visible.Align the MOPO-710 base plate such that the 532nm beam are centeredthrough the two outermost window ports of the MOPO-710. Both horizontal and verticaladjustments to the MOPO-710 may be required.Use levelling indicators to ascertain that the MOPO-710 remains horizontalfollowing any height adjustment.Secure the MOPO-710 to the optical table by using the four foot clampsprovided.Remove the MOPO-710 cover.At high energy, these pulses can cause permanent eye damage. Alwayswear appropriate eye protection when making adjustments to the MOPO-700.
