✦ Synopsis

We report on the development of a high pulse energy femtosecond Yb:KGd(WO4)2 laser pumped by a fibercoupled diode module. Passive mode locking was initiated using a semiconductor saturable absorber mirror. The laser produced 420 fs pulses with up to 145 nJ of energy at a repetition rate of 14.5 MHz. The output spectrum was centered at 1030 nm. At the lower pulse energy of 100 nJ the laser produced 300 fs long pulses.

We have demonstrated a simple and compact tunable dual-wavelength Yb 3+ :KGd(WO4)2 (Yb:KGW) laser. The laser is diode pumped through an optical bifurcated fiber and an adjustable beamsplitter. Thanks to two transversally chirped volume Bragg gratings (TCVBG) used as output couplers, the frequency di
