Actively Q-switched DPSS laser; pulse width <2 ns; repetition rate up to 50 kHz; very low jitter; 1064 nm and harmonics down to 355 nm
Utilising advanced technology, SPOT actively Q-switched DPSS lasers provide a short pulse output (pulse widths <2 ns) at repetition rates from single shot up to >50 kHz with very low jitter. The series features fundamental YAG wavelength at 1064 nm and harmonics down to 355 nm. The compact design enables the lasers to be easily integrated into scientific instrumentation.
Applications include laser induced fluorescence, time resolved fluorescence, micromachining, biotechnology, plasma generation, remote sensing, photo acoustic imaging, MALDI mass spectrometry and MALDI imaging.
SPOT laser systems consist of a laser head with a separate power supply unit. Both units are connected with a cable which is hard wired into the laser head while having a 37 way ‘D’ connector for connection to the power supply unit.
The SPOT DPSS laser series feature simple, user-friendly control with the minimum of user defined parameters. The systems are designed as fixed power level devices under automatic operation, or power can be varied by adjusting the pump diode current via RS232 interface.
