Ultraviolet to Infrared Picosecond Diode Laser Heads - LDH 375 to 1550

The LDH Series picosecond diode laser heads produce light pulses as short as 70 ps (FWHM, on selection down to 50 ps for some wavelengths) at repetition rates from single shot to 80 MHz (depending on the wavelength). For selected wavelengths peak powers up to 1 W can be emitted. The short pulse width perfectly matches the time resolution of mainstream detectors, yet at a price ten times lower than that of commonly used Ti:Sapphire or Argon ion lasers. A combination of interchangeable LDH Series laser heads, together with the PDL 800-B, PDL 800-D, PDL 808 "Sepia" or PDL 828 "Sepia II" driver satisfies the demand for compact and affordable excitation sources that cover a wide range of wavelengths. Previously, nanosecond flash lamps with low repetition rates or expensive and bulky Ti:Sapphire lasers were the typically employed sources.They require extensive maintenance and considerable experience to run in daily work. The LDH Series pulsed diode laser sources offer the benefits of cheap and compact integrated turn-key systems along with the high repetition rates desired for fast applications like Time-Correlated Single Photon Counting (TCSPC). These features open the door for entirely new routine applications beyond the research lab, e.g. in bioanalytics, biochemistry, genetics, semiconductor characterisation and quality control.
