Carrier-envelope-offset-stable Yb:CaF2 laser pumped by a single-mode laser diode

We present a carrier-envelope-offset-stabilized, self-referenceable Yb:CaF 2 oscillator. Employed single-mode diode pumping scheme enabled us to achieve low-noise operation with sub−70 mrad integrated phase noise of the locked f ceo beat note (1 Hz – 1 MHz).
