1. Due to continuous improvements all specifications are subject to change. Unless stated otherwise all specifications are measured at fundamental wavelength and maximum pulse repetition rate. The parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture.
2. Factory-set pulse repetition rate is fixed at max repetition rate shown in the table. In internal triggering mode repetition rate can be divided by integer number down to f/2, f/3, f/4,.. 1 Hz.
3. When pulse energy is presented in xx/yy format, first number is for 1064 nm wavelength version, second – for 1053 nm version.
4. At FWHM level at fundamental wavelength, measured with 350 ps rise time photodiode. Short pulse duration version is available, with pulse duration shorter by approx 50%. Inquire for detailed specifications.
5. Measured during 30 seconds operation after warm-up.
6. Over 8 hour period after 20 minutes of warm-up when ambient temperature variation is less than ±2 °C.
7. Full angle measured at the 4σ level.
8. Beam diameter is measured 20 cm from laser output at the 4σ level.
9. In respect to falling edge of pump diode triggering pulse.
10. Q2 is compatible with our attachable second harmonic generator (model SHG) and all models of stand-alone H-SMART harmonics generator. Pulse energies presented here are maximum values. Please refer to harmonic generator datasheets for detailed specifications.
11. Motorized attenuator intended to be attached to the laser housing. Transmission can be changed remotely trough laser web-server control interface.
12. Power adapter dimensions might differ from indicated here, depending on model.
13. Laser can be powered from appropriate 12 or 28 VDC power source. Please inquire for details.
Description
The Q2 series represents a new generation of diode-pumped solid-state (DPSS) Q-switched lasers, designed for demanding applications that require high peak power and exceptional beam quality.
These fully air-cooled lasers combine efficiency, reliability, and compactness, eliminating the need for external chillers or water-based cooling systems.
Powerful and Flexible Performance
The Q2 diode-pumped nanosecond laser can be configured to deliver up to 80 mJ pulse energy at 10 Hz or 20 mJ at 100 Hz, offering exceptional versatility for both low- and high-repetition-rate applications.
The laser supports operation with either Nd:YLF (1053 nm) or Nd:YAG (1064 nm) crystals.
Thanks to the superior thermal properties of Nd:YLF, the Q2 maintains stable beam divergence and profile from single-shot operation to the maximum repetition rate.
In its short cavity configuration, pulse duration can be reduced by up to 50%, reaching peak powers exceeding 16 MW at 40 mJ pulse energy — ideal for applications requiring ultra-fast, high-energy pulses.
Advanced Cooling and Maintenance-Free Design
The Q2 air-cooled laser uses a thermoelectric cooling system, eliminating common issues associated with traditional water cooling such as leaks, contamination, and maintenance overhead.
A detachable, fan-cooled heatsink allows flexible integration — the laser can be mounted on a user-supplied cold plate or other cooling systems when required.
All laser electronics are integrated into a single, compact housing.
The only external components are a lightweight controller box providing interface control and a 12 VDC or 28 VDC power supply (30–100 W depending on model).
This streamlined design ensures plug-and-play operation and minimal maintenance requirements.
Smart Control and Connectivity
The Q2 DPSS laser features an Ethernet-based control system with a built-in web server — no software installation required.
It can be accessed and controlled directly from any computer or mobile device via a standard web browser.
For custom setups, an API is provided for full integration with external instruments or automation systems.
In internal triggering mode, low-jitter synchronization pulses are available with up to 300–450 µs lead, depending on the lasing wavelength.
In external triggering mode, the laser can be precisely triggered using an optional delay generator.
Harmonic Generators Compatibility
The Q2 platform supports efficient wavelength conversion using QLI’s H-SMART generator modules, enabling operation up to the fifth harmonic.
This flexibility makes the Q2 ideal for applications requiring UV, visible, or IR laser output from a single, compact source.
