RealSubns® MCA-R Series 1.5ns Microchip Laser
RealSubns® MCA-R Series 1.5ns Microchip Laser

MCA series microchip lasers are RealLight’s self-developed, passively Q-switched diode-pumped solid-state lasers. The integrated design of diode-pumped module and laser crystal brings convenience to installation and integration due to the compact size. This series of lasers offers miniaturized drive boards specially for meteorological radar application, featuring small size, low power consumption, and can be used in high altitude, large temperature difference and other harsh environment. Custom dual wavelength laser solutions are available for MCA series, such as 1064nm&532nm, 1064nm&355nm or others.

1. *Side laser outlet configuration.
Lasers with repetition rate < 20kHz are positive-edge-triggered, and lasers with repetition rate > 20kHz are gate-triggered.
All systems rely on 5V TTL levels and have SMA interfaces for external triggering input. See mechanical specifications for more details!
2. External beam expanders are available upon request, to meet smaller divergence requirements.
