Picosecond lasers cover a wavelength range from 380 nm to 1550 nm, delivering optical pulses with pulse widths as short as 27 ps. They offer adjustable repetition rates from 1 Hz to 100 MHz with a 1 Hz resolution. Advanced models support Burst mode, making them ideal for fluorescence lifetime measurements, assays with varying lifetimes, and other time-resolved applications. These compact, user-friendly, and plug-and-play laser systems are designed to meet the needs of a wide range of applications.
