We present a diode-pumped regenerative amplifier based on an $\mathrm{Yb}\text{:}{\mathrm{CaF}}_2$ crystal optimized to produce short pulses for various repetition rates ranging from $100\mathrm{Hz}$ to $10\mathrm{kHz}$ . The shortest pulse duration generated is $178\mathrm{fs}$ , and the corresponding energy is $1.4\mathrm{mJ}$ before compression ( $620\mathrm{\mu J}$ after), at a repetition rate of $500\mathrm{Hz}$ for $16\mathrm{W}$ of pump power. The bandwidth is $10\mathrm{nm}$ centered at $1040\mathrm{nm}$ . Higher repetition rate regimes have also been explored, allowing an optical-to-optical efficiency up to 10% at a high repetition rate.
