Optical differentiation and multimillijoule approximately 150 ps pulse generation in a regenerative amplifier with a temperature-tuned intracavity volume Bragg grating.
An optical differentiation in a regenerative amplifier with a temperature-tuned volume Bragg grating (VBG) as an intracavity spectral filter is demonstrated for the first time, to the author's knowledge. 12 mJ approximately 150 ps pulses with a TEM(00) beam profile have been generated at the 5 Hz repetition rate in the nanosecond-pulse-seeded regenerative amplifier with a VBG that is temperature detuned from the central wavelength.
