The laser may be of any suitable type and wavelength ... locked lasers separated in frequency by the resonator's free spectral range. It can be demodulated by a fast photodiode to produce a ...

the molecule's signal is separated from the laser pulse itself, making it easier to detect the vibrational response in a background-free manner. This allows scientists to identify specific ...

Additionally, the device operates using a simple, free-running distributed feedback laser diode ... stable operation across 90% of the free spectral range, eliminating the need for complex ...

When the Ti:Sapphire laser was first invented ... No other material can offer: 1) spectral outputs that range from ultra-narrow single frequencies to wide bandwidths spanning several hundred ...
