Picosecond Lasers for TCSPC

Becker & Hickl diode lasers deliver picosecond light pulses at high repetition rates. Thus, they are perfect with advanced TCSPC techniques. The lasers can also have a CW mode to generate a continuous high-power beam of light.

Both in the picosecond pulsed mode and in the CW mode the output power is stabilized by internal power regulator loops. The lasers feature low intensity noise and high power stability.

The lasers have integrated beam profile correction optics. They deliver beams approximating circular cross-sections with low astigmatism. Lasers can be free space coupled, or fiber coupled.

Output power of the lasers can be controlled by external signals, and have fast reacting on/off control input. The input can be used to control multiple lasers. Synchronization inputs allow the lasers pulse train to be synchronized with these other lasers.

The drive electronics are integrated into the laser head. Thus, all that is needed is 12 volts DC. Laser safety include a connection box with key switch and emission indicator.

These high-performance lasers are fully compatible with the Becker & Hickl SPC or Simple Tau TCSPC devices. They also form an essential element of the DCS-120 confocal scanning systems, as well as the FLIM systems for a wide range of other laser scanning microscopes.
