The QLD0593 series consists of compact visible light lasers with wavelengths of 532, 561 and 594 nm that use a DFB laser and wavelength conversion element. Diode-pumped solid-state lasers (DPSS lasers) are primarily used in this wavelength band, but they have drawbacks including the inability to modulate. Our lasers use a built-in semiconductor laser that ensures highly stable, high-speed modulation and realize low power consumption by applying GaAs-based semiconductor laser technology. QLD0593 series lasers come in small packages of our own design and can be supplied in a fiber pigtail design when required by customers. They can be used in flow cytometers for biomedical applications as well as in sensor applications for microscopes and spectroscopy.
