Mode-locking of an Yb:KYW laser with carbon nanotubes
- Materials were purchased (see budget plan).
- Cavities are designed and all necessary materials available.
- A 1 GHz Yb:KYW cavity with QD-SESAM was designed and evaluated, giving 2ps pulses with an average power of 100mW in stable mode-locking regime.
- A 100 MHz cavity was designed and is in construction.
- Initiation of technology and knowledge transfer from single wall carbon nanotube (SWCNT) specialists in South Korea established, four samples received and future collaboration planned.
- Process and experiments for spin coating SWCNT is planned and ready to begin.
- Spin coat PMMA to bulk mirror substrates and characterize optical properties.
- Spin coat SWCNT with PMMA with different thickness and characterize optical properties (linear and nonlinear absorption as well as transient behavior) using the 100 MHz laser.
- First evaluation of SWCNT samples on a bulk mirror substrate first inside the 100 MHz cavity.
- Following that, evaluation of the SWCNT in the GHz cavity and spin coating onto other cavity components.
