(color online) Fizeau wavemeter interference pattern for the seeded injection laser. Upper and lower traces correspond to low and high-resolution Fizeau wedges, respectively. The horizontal axis shows the position of the interference signal (arb. units) and the vertical axis indicates relative intensity of the signal (arb. units).
