Diode-Pumped Solid-State Micro Laser

532 nm wavelength micro lasers with short pulses, high peak power together with high reliability.

High peak powers with sub-nanosecond pulse lengths or high repetition rates at wavelengths 532 nm and are now available from Standa. This family of highly reliable, solid-state lasers consists of a power supply unit and laser head. The power supply unit includes a laser diode (LD) driver, fiber pigtailed LD, and internal pulse generator. The laser repetition rate can be operated in three different modes, and set by STANDA from single pulse or to max repetition rate agreed with customer in either pulsed LD pumping mode. STA-01SH – produces pulses of second harmonic.

  • TEM00 and pulsed spectral structure SLM

Applications:

  • Pump source for harmonic generators,optical parametric oscillators and amplifiers(using periodically poled KTP or LiNbO3 crystals)
  • Low-coherence “white light” interferometry
  • Test and measurement systems
  • Optical coherence tomography
  • Two-photon microscopy
  • Fluorescence microscopy
