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.

The QC4LD0593 series is one of the world's smallest plug-and-play visible light sources, combining a compact visible laser @ 532 nm, 561 nm, or 594 nm (QLD0593 series) with a built-in driver. Its free space output with high-quality elliptical beam is suitable for flow cytometry. Low power consumption and short warm-up time contribute to higher performance of biomedical equipment. A fiber pigtail type (QC4LD0561 series) is also under development.
＊We also offer a tailor-made multi-color compact laser light source includes up to 4 wavelengths in one module: one wavelength from QLD0593 series (532, 561, or 594 nm) and up to 3 wavelengths from TO-CAN series (405, 488, 640, 660, 685, 785, 830, 850, 905 nm).
