Compression of low energy ultrashort laser pulses using a hollow core fiber (HCF) filled with 1-1 difluoroethane (C2H4F2), also known as R152a, is demonstrated. A 45 fs, 16 µJ Ti:Sapphire laser pulse… (More)
We introduce hydrofluorocarbon molecules as an alternative medium to noble gases with low ionization potential like krypton or xenon to compress ultrashort pulses of relatively low energy in a… (More)
Starting in the mid-nineteenth century, people from Lebanon began moving in large numbers to North and South America, Africa and Northern Europe. Today, the Lebanese diaspora is estimated to be… (More)
We introduce hydrofluorocarbon molecules as a valuable alternative to conventional noble gases to compress 100 pJ level ultrashort pulses. We demonstrate efficient compression down to 15.6 fs for 170… (More)
We show that hydrofluorocarbons can be used for efficient hollow core fiber pulse broadening. Fivefold compression, 45 fs down to ~9 fs, of low-energy titanium-sapphire laser pulses $(\sim 16\mu… (More)
