Photonics Industries (PI), The Pioneer of Intracavity Solid-State Harmonic Lasers, has received the Laser Focus World 2018 Innovators Award for increasing to:
• >1mJ pulse energy (~2 to 3x to the next closest competitor) at 40kHz
• UV output (at 355nm)
of its DSH Series UV ns laser. The DSH-355-40 laser is a compact, nanosecond UV laser utilizing patented intracavity UV generation with Total Pulse Control (e.g., individually triggered pulses on demand) to achieve up to 50W of output power.
Key Patented Technologies
Owing to key patented technologies that provide:
• non-consumable THG crystals
• with no indexing required
intracavity harmonic generation is an inherently more efficient harmonic conversion that provides:
• better pulse to pulse stability <1% P-P stability
• mode quality typically M2 < 1.1
• much simpler, more compact laser configuration.
In addition to this intracavity UV generation, the end-pumped geometry of Photonics Industries’ DSH UV Series lasers results in even better mode quality with field replaceable pump diodes, for the lowest COO possible.
With standard Total Pulse Control features such as PEC and Duty Control, pulse energy and pulse width, for example, can be held constant over wide ranges of repetition rates for tight process control at fast speeds. Combined with the higher power, faster throughput results in significantly lower costs per part.
Increasing the power and pulse energy of UV lasers is in demand due to the desire to increase the speed in applications ranging from semiconductor wafer dicing to mobile/FPD manufacturing applications. With the DSH-355-40 laser, industrial micromachining customers can process materials at a much quicker, more efficient rate, expediting their manufacturing processes with small amount of cost increase to yield 2x or more throughput for large number of applications. Furthermore, the high pulse energy of >1mJ enables new applications and spatial scaling techniques which were not possible in the past.
