Abstract:
We have developed a combined Ti:Al(2)O(3)/Cr:LiSrAlF(6) laser system capable of producing terawatt pulses with a duration of 120 fs at a 1-Hz repetition rate. Chirped-pulse amplification in Ti:sapphire produces compressed 45-mJ pulses. Further amplification in flash-lamp-pumped Cr:LiSrAlF(6) produces 150-mJ compressed pulses with no significant effect on beam quality or pulse shape.
