Figures 1 and 2 illustrate that the output signal inherited the aberration of the pump beam as its phase is modulated in the presence of spatial walk-off. Therefore, high-frequency modulation in the pump phase should be suppressed as much as possible to obtain a good-quality signal beam in the OPA process.
The phases of the signal ([[PHI].sub.s]), pump ([[PHI].sub.p]), and idler ([[PHI].sub.i]) are known to be fulfilled by the following relationship without walk-off effect and when the phase-matching condition is satisfied:
Equations (4) and (5) show that the phase of the output signal is independent of the pump phase, whereas the phase of the idler beam is related to the difference between [[PHI].sub.s] and [[PHI].sub.p] as the walk-off effect is neglected.
Thompson's pennant-clinching blast in 1951 was an extension of the regular season and not a postseason contest A player clinching a postseason series with a walk-off
home run has been accomplished eight times in major league history.
The win marked the eighth walk-off
victory this year for the Boomers (44-46).
Bill Mazeroski and Joe Carter are the only hitters to club walk-off, World Series-ending homers.
Carlton Fisk's 12th inning walk-off homer that hit the foul pole at Boston's Fenway Park in Game 6 of the 1975 World Series came off Reds pitcher Pat Darcy.
Bill Mazeroski of the Pirates hit his Game 7 walk-off home run against Yankees pitcher Ralph Terry in the 1960 Fall Classic.
With one out, Ryan Gridley singled to center field, earning the Snappers the walk-off
Jack Parenty handed Schaumburg a sixth walk-off
win of the season by singling through a drawn in infield to knock in Clint Hardy.
Towns fell behind in the count 0-2 to Evansville closer Mitch Aker before battling back to even things and then tucking a 2-2 pitch inside the left field pole for a walk-off
homer, just the third in team history.
Bronfman called the walk-offs
a sign of Birthright's success.
