The Tristar™ laser is an excellent choice for demanding UV laser applications where highly focused spots, precision positioning, and the highest possible throughput are necessary.
With a short 25 ns pulse width, the Tristar UV laser generates the high-intensity peak power necessary for precision scribing applications. For scribing LED substrates, this means cleaner scribe lines, higher throughput, and higher brightness LEDs. The Tristar UV laser’s higher peak power allows the removal of material using short bursts of high energy, thus reducing undesired thermal effects which can overheat the work surface. This translates to higher throughput and less heat-related damage to the individual LED devices. The Tristar UV laser is pumped with a field-replaceable diode. This unique diode module can be easily replaced in the field and last more than double the industry average for other Q-switched lasers.
| Model | Spatial Mode | Average Power | Wavelength | Repetition Rate (nominal) | Pulse Width | Peak Power | M2 | |
| Tristar 355-1 UV Laser | TEM00 | >1 W at 100 kHz | 355 nm | 100 kHz | <25 ns | 0.4 kW | <1.2 | |
| Tristar 355-3 UV Laser | TEM00 |
>3 W at 50 kHz >2 W at 90 kHz | 355 nm | 90 kHz | <25 ns | 0.9 kW | <1.2 | |
The Tristar compact UV laser is designed as a hands-free, OEM and industrial laser system. It is easy to service in the field with user replaceable:
Laser head
Power supply
Fiber and diode assembly
Output optic
The Tristar design makes routine wear parts easy to change to significantly shorten mean time to repair (MTTR) and increase total system uptime.
In addition to solid reliability, outstanding performance makes Tristar the laser of choice of 355 nm industrial manufacturing applications. Key features include:
Compact Size – for ease of integration
Modular Design – for easy field service, including:
Field replaceable laser output window – corrects for burn spots caused by airborne particulates generated from the ablation process
Field replaceable diode/fiber – the diode/fiber can be easily replaced in the field, without requiring costly tool re-alignment or system downtime
Interchangeable laser head and power supply
EternAlign™ Optics – our rugged I-beam laser housing and EternAlign™ optics eliminate potential damage and optical misalignment resulting from vibration and shipping
User Friendly – clear, logical command structure and easy graphical user interface make the HIPPO quick and easy to integrate
Harmonic Crystal Shifters – compensate for power loss due to crystal degradation, allowing instant restoration of the laser to full power
ALPS – our unique Active Laser Purification System™ maintains the laser cavity clean and dry over the life of the laser to significantly extend laser life
Data Logging – keeps a log of key performance parameters over time and provide a powerful service feature and product reliability tool
Spectra-Physics Q-Switched DPPS lasers have been designed for micromachining applications in a 24/7 manufacturing environment. Founded in 1961, Spectra-Physics has shipped thousands of lasers into the key industrial markets where 24/7 system operation and the demand for system uptime makes product reliability a key element in laser selection.
Microelectronics: processing and repair of semiconductors, flat panel displays, PCBs, LEDs, electronic packages, storage media, etc.
Solar: scribing, drilling, doping, marking, dicing etc. of photovoltaic cells and modules
Spectra-Physics industrial lasers have a number of unique design features that significantly increase the both laser life and uptime. Our diodes typically last twice the industry average. The lasers’ modular design isolates known wear components and key failure mechanisms into small components (such as diodes, fibers, output window, shutters, and harmonic modules) that are easy to change in the field without costly tool realignment. This lowers service inventory holding costs while shortening Mean Time to Repair (MTTR).
Our proprietary optical alignment system (EternAlign™) and rugged laser housing virtually eliminate alignment failures that can occur with vibration and shock during shipping. The sealed laser resonator and unique filtration system (ALPS) significantly extends the life of the laser by keeping the air inside the laser clean, dry, and free of volatile organic compounds from out-gassing.
And finally our automatic data logging software monitors all key laser performance parameters over the life of the laser, providing a powerful service feature and product reliability tool.
