The QLD0593 series is a compact visible laser with wavelengths of 532 nm, 561 nm, and 594 nm. In this wavelength range, Diode-Pumped Solid-State Lasers (DPSS lasers) have been mainly used; however, there have been issues such as the inability for modulation operation. This series utilizes our patented technology combining DFB laser with SHG (second harmonic generation) crystal, enabling high-speed modulation, output power stability, low power consumption, and a compact package. Its free space output with high-quality elliptical beam is suitable for flow cytometry. We also offer a fiber pigtail type (QLD0561 series). An option with driver for picosecond pulsed operation is available.
