High Power Diode Pumped Short Pulse Lasers Based on Yb:KGW Crystals for Industrial Applications
A diode pumped, ultrafast Yb:KYW laser system utilizing chirped pulse amplifica tion (CPA) in a dual slab regenerative amplifier (RA) with spectral shaping of seeding pulse from a master oscillator (MO) has been developed. A train of compressed pulses with pulse length of 181 fs, repetition rate up to 500 kHz, and average power exceed ing 15 W after compression and pulse picker was achieved.
