Tunable Lasers Overview
Tunable lasers using an optical parametric oscillator (OPO) are capable of producing continually tunable output wavelengths from 410 nm to 2300nm, and with the addition of a second harmonic generation stage, the wavelength range can be extended down to 210 nm. Additionally, integral compact spectrometers for real-time monitoring of OPO output wavelength are available. These pulsed lasers provide a variable pulse repetition rate up to 100Hz, with a typical pulse width of 5ns and pulse energy or 5 mJ. With spectral linewidth, less than 6 wavenumbers, these compact, low power consumption tunable lasers are ideal for non-linear spectroscopy, photo-acoustic imaging, metrology, and remote sensing applications.
