The LDH-I Series from PicoQuant are Smart Laser Heads that operate at a wavelength of 375 - 1550 nm. They have a wavelength accuracy of ± 10 nm and deliver an average power of 0.1 mW - 150 mW & 2 mW - 200 mW (CW). These linearly polarised laser heads have a peak-to-peak power stability of 3 % and rms power stability of 1%. They have a spectral width below 1 nm (CW), 2 nm - 8 nm (less than 900 nm), and 10 nm - 20 nm (above 900 nm). These laser heads have a pulse duration of 40 ps - 250 ps (at FWHM) and maximum pulse repetition rate of 50 MHz - 100 MHz. They operate in pulsed, bursts, and continuous wave operation modes.
The LDH-I Series laser heads have a beam divergence of 0.11 mrad (parallel) and 0.32 mrad (perpendicular). They have a numerical aperture of 0.55 and optical focal lengths of 4.5 mm & 9 mm. These laser heads have a polarization extinction ratio (PER) above 1:10 and side mode suppression ratio (SMSR) below 0.01. They are compatible with the Taiko PDL M1 driver and uses a Peltier cooler. These laser heads are available in a module that measures 76 × 207 mm (cylinder) and 207 × 77 × 83.7 mm (cuboid) with an optional fiber coupling. They are ideal for time-resolved measurements, life science, FLIM, FCS, STED, material science & semiconductor diagnostics, metrology & calibration, ranging, LiDAR, and seeding applications.
