Ultrafast Nonlinear Optics:
Microsecond lasers
- Evolution - the diode-pumped intra-cavity doubled Nd:YLF laser is capable of producing Q-switched pulses with an average energy > 20mJ at 527nm at repetition rates of above 1kHz.
Nanosecond lasers
- Quata-Ray Lab 170 - Nd:YAG high power laser with a 10 Hz repetition rate, 1st harmonic wavelength 1064 nm at 850 mJ/pulse and a pulse width of 8-12 ns
- Quanta-Ray Pro 250 - Nd:YAG high power laser with a 10 Hz repetition rate, 1st harmonic wavelength 1064 nm at 1500 mJ/pulse and a pulse width of 8-12 ns
Femtosecond lasers
- Tsunami - Femtosecond Mode-locked Ti:Sapphire Laser is a solid-state laser capable of tunable laser operation over a broad range of near infrared wavelengths from 690nm to 1080nm. The pulse width of the Tsunami output is about 130 femtosecond and peak power is more than 140kW at a wavelength of 790nm with a pulse repetition rate of 82MHz.
- Spitfire - Regenerative amplifier is designed to amplify single pulses from a mode-locked Ti:sapphire laser. Typically, an input pulse of energy of a nfew nanojoules can be amplified to over 1mJ. This represents an overall amplification of greater than 106.
