Q-SPARK——高达20 mJ @ 1.5 ns

简介

Q-SPARK is diode pumped, water-free, Q-switched laser designed for wide range of applications that require sub-nanosecond or nanosecond pulses with up to 20 MW peak power.
We optimized our innovative water-free laser crystal end-pumping technology to produce Gaussian-like, low divergence, sub-nanosecond pulses in compact and energy-efficient package.
Passively Q-switched Q-SPARK version can be configured to produce pulses as short as 750 ps and with more than 5 mJ pulse energy. E-O Q-switched version delivers up to 20 mJ with Laser is monitored and controlled trough Ethernet port via build-in web-server. API is also provided for integration with user devices.

Laser functionality can be further extended by wide selection of auxiliary equipment:

? Up to fourth harmonic output wavelength can be produced build-in harmonics generator, located inside laser body. See datasheet below for pulse energy specifications.
? Pulse energy can be adjusted with our attachable motorized attenuator for fundamental or harmonic wavelength beam.
? Pulse energy can be monitored by our attachable pulse energy monitor with analog and/or digital output.
? Residual harmonic generator wavelengths can be accessed with optional auxiliary exit port.
? Fiber coupled output is available by request. Please inquire for detailed specifications.
