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.
Designed and manufactured by Becker & Hickl – High Performance picosecond diode lasers with wavelengths from the NUV to the NIR. All bh pulsed diode lasers work with simple +12V power supply or pull their power from the USB port of a PC or Notebook Computer.
Other features are high repetition rate, short pulse width, unprecedented timing and power stability, and extremely low electrical noise level.
The complete driver electronics is integrated in the laser module. All bh diode laser modules are directly compatible with the bh TCSPC modules.
The BDS-SM devices are combined pulsed picosecond and CW diode lasers in a small industrial-size case. All the pulse driver and control circuitry is contained in the laser head. All that is needed to operate the lasers is a +12V power supply and a few control signals for setting repetition rate and optical power. Pulse repetition rate in pulsed mode is 20, 50, or 80 MHz, other repetition rates are available on request or can be obtained by external triggering. Pulse width is in the range of 40 ps to 100 ps.
Single-Transversal Mode Picosecond and CW Diode Laser
Pulse Width Down to 30 ps
Excellent Timing Stability – No Warm-Up Time Necessary
The BDU-SM series picosecond diode lasers are fully controlled and powered via a USB interface. Available wavelengths range from 375 nm to 785 nm. The lasers are available with circular free-beam output, and with single-mode fibre output.
As the BDS-SM lasers, also the BDU-SM lasers feature extraordinarily high timing stability and intensity stability. The optical pulse versus the electrical trigger output shifts by no more than 2 picoseconds over 10 minutes, even immediately after turn on. The power is stable within 1 %. No warm up-time is necessary for stable operation. Small size, absence of external components, and easy control of the laser parameters make the laser first choice for quick setup of experiments in a typical laboratory environment.
