ASE contrast improvement with a non-linear filtering Sagnac interferometer
A new method to improve the temporal contrast of an ultra-short laser pulse has been developed. This technique uses a Sagnac interferometer in combination with a non-linear medium. A phase shift induced in the ultra-short pulse by non-linear effect separates it from the amplified spontaneous emissio...

| description | A new method to improve the temporal contrast of an ultra-short laser pulse has been developed. This technique uses a Sagnac interferometer in combination with a non-linear medium. A phase shift induced in the ultra-short pulse by non-linear effect separates it from the amplified spontaneous emission background. Experiments with a 1kHz, 55fs, 1mJ Ti:Sa laser were performed. The temporal contrast measurements have shown a contrast improvement of four orders of magnitude. |
