Features
- Femtosecond pulse conversion to < 20 cm-1 spectral bandwidth
- 240 nm – 10 μm tuning range
- Up to 4 mJ pump pulse energy
- High output stability
TOPAS-SHBC-400 combines a second harmonic bandwidth compressor (SHBC) and an optical parametric amplifier (OPA) for the generation of tunable pulses with a spectral bandwidth of 3 – 20 cm-1 when pumped by femtosecond pulses with a spectral bandwidth of 150 – 500 cm-1. The device is designed to be pumped by a fundamental harmonic of a femtosecond Ti:Sapphire laser and covers a wavelength range from 480 to 2400 nm. Optional frequency mixers extend the tuning range down to 240 nm and up to 10 μm.
TOPAS-SHBC-400 specifications are given for the following SHBC output parameters:
- 400 nm wavelength
- 0.5 mJ pulse energy
Note 1: Specifications depend on SHBC output wavelength. If it differs from the value above, contact sales@lightcon.com.
Note 2: TOPAS-SHBC-400 output pulse energy scales linearly in 0.5 – 2 mJ range, provided the device is installed and optimized for particular pump energy. The device has to be re-optimized if the pump energy changes more than 10% from the installation value.
- Normalized to average pulse energy, NRMSD.
