Transient stimulated Raman scattering (SRS) of 0.3 ps 515 nm laser pulses in \rmBaWO_4 BaWO_4 crystal was experimentally demonstrated with efficiency up to ∼20\%∼ 20% for …
We demonstrate what we believe to be a new approach to energetic picosecond 10.2-µm pulse generation based on nonlinear mixing of subnanosecond single-frequency 1338-nm …
The simple mid-IR laser source based on femtosecond Ti: Sapphire laser and successive frequency conversion of its stretched up to 50 ps pulses in SrMoO 4 Raman-active crystal …
We experimentally carried out frequency conversion of a chirped and stretched up to 200 ps near-IR 90 fs Ti: Sapphire laser pulse into the mid-IR through difference frequency …
