Lasers

Many industrial micro-processing applications that use femtosecond lasers have been developed in a variety of sectors, including medical and semiconductors. To access new large-scale applications such as surface texturing, however, robust industrial-grade beam shaping solutions need to be combined with femto-second lasers. Cailabs and​​ Light Conversion​​ have developed a partnership to demonstrate the quality and robustness of their solution using a Canunda-Pulse beam shaper and a​​ CARBIDE laser.

The paper explaining this collaboration is entitled, “Beam shaping to scale up micro-processing.”

A research team converted a Light Conversion​​ PHAROS​​ Yb laser to a tuneable ultrafast, deep ultraviolet source (208 nm to 306 nm) at µJ-level and high repetition rate, in a very compact setup.

A published paper, entitled “Efficient and compact source of tuneable ultrafast deep ultraviolet laser pulses at 50 kHz repetition rate,” describes this experiment.

The FC-W-H series Fiber Coupled Laser System from CNI Optoelectronics Tech combines laser diode, fiber coupled optics, laser power supply, LD current,​​ and temperature control in one box. Its compact size and convenient functions, such as power adjustment, temperature control, LED display, etc., make it quite suitable for pumping, scientific research, industrial, and medical applications.

Possible wavelengths for this laser are: 375, 405, 445, 447, 450, 455, 460, 462, 520, 793, 808, 880, 915, 940, 976t and 980 nm.

A team of researchers, including Scott Hamlin from​​ MegaWatt Lasers (MWL),​​ demonstrated that langasite (LGS) enables efficient Q-switch operation of Cr:Er:YSGG lasers at 2.79 µm. The laser is flash lamp-pumped and electro-optically (EO) Q-switched. They report 300 mJ output energy at 15 ns pulse duration at a 3​​ Hz repetition rate, which is, as far as the team knows, the record result documented to date at​​ this wavelength.

Light Conversion built its OPCPA systems using in-house-developed front ends, specifically​​ PHAROS​​ and​​ CARBIDE​​ femtosecond lasers. Both of these laser series offer industrial-grade stability and reliability. Thus enabling the ORPHEUS-OPCPA system to deliver few-cycle, CEP-stable pulses in a compact space.

Since the development of the SYLOS at ELI-ALPS, the company has produced over five high-energy OPCPAs​​ with sub-10 femtosecond pulses reaching hundreds of millijoules. Multiple table-top ORPHEUS-OPCPAs were also produced. These products are being applied​​ in​​ high-energy attosecond pulse generation, laser electron​​ acceleration, and nuclear waste​​ decomposition​​ applications.

Optics

If you are working with Raman spectroscopy and looking to optimize performance, check out​​ Iridian Spectral Technologies’ latest article, entitled​​ How Custom Raman Edge Pass And Dichroic Filters Optimize Instrument Performance.”

This article describes how best to choose and customize optical filters, such as​​ edge filters and dichroic filters,​​ for your applications.

The overall costs for data center interconnects play a major role,​​ because large quantities​​ of transceiver devices and fiber optic cables are required. Delivering high optical performance at the lowest possible cost is, therefore, critical for manufacturing datacom filters. Iridian Spectral Technologies designs and manufactures​​ custom-tailored optical filters​​ and​​ etalons​​ to fulfill the requirements for your datacom filter solution at the highest optical quality, robustness, reliability, and cost-sensitivity.
