Fig. 1. Broadband deep-UV laser source.
In our laboratory, there are several ultrafast spectroscopy techniques that are routinely used/developed to study carrier dynamics in molecular systems and solid-state nanomaterials, and there is a great opportunity to gain hands-on experience in using them and developing new methods. All of them are powered by laser sources that generate ultrashort optical pulses at high repetition rates.
- “Pharos” laser system provides 1027-nm 170-fs laser pulses at repetition rates of up to 600 kHz
- Tunable noncollinear optical parametric amplifier (NOPA) from Light Conversion provides 9-18 fs pulses with tunable central wavelength (470-950 nm) at repetition rates of up to 200 kHz.
- Lab-built NOPA provides 9-18 fs pulses with tunable central wavelength (470-950 nm) at repetition rates of up to 200 kHz.
- Broadband deep ultraviolet (UV) laser source provides 10 fs pulses with tunable wavelength (250-320 nm) at high repetition rates of up to 200 kHZ (Fig.1) .
