HeCd Lasers

HeCd LASERS

Helium Cadmium (HeCd) lasers are the ideal wavelength of choice for Raman and Photoluminescence (PL) excitation at 325nm and 442nm.
Technology From: Kimmon Koha Co., Ltd.

HeCd Lasers

Power Output: 2mW-50mW, 14mW-180mW
Wavelengths: 325nm, 442nm

Helium Cadmium (HeCd) lasers are the ideal wavelength of choice for Raman and Photoluminescence (PL) excitation at 325nm and 442nm. Kimmon Koha Co., Ltd build, produce, assemble, and process almost everything for their HeCd lasers in-house, allowing them to control the whole manufacturing process.

One of the unique capabilities of the production system is the ability to process raw quartz from their own quartz mines and produce HeCd laser tubes in-house. These capabilities translate into higher quality products for customers.

Another aspect of the Kimmon manufacturing system is the unparalleled feature of gathering data on each laser system. Over 500 pieces of data are gathered on each laser shipped. This data collection enables the prevention of potential problems with each laser prior to shipment.

Laser Diodes for Raman Spectroscopy

Laser Diodes for Raman Spectroscopy

These lasers are diffraction limited and can focus to micron size spots, unlike the higher power lasers, which at best can focus to a 100 micron spot size.
Technology From: Micro Laser Systems

Laser Diodes for Raman Spectroscopy

Power Output: 28mW-490mW
Wavelengths: 405nm-785nm

For many Raman spectroscopy applications, about 100mW in a small beam is all that is required. To date this has only been satisfied by higher power (300-500mW) multimode lasers with line widths of 0.5nm or larger.

These lasers are designed to give diffraction limited output with narrow line width and high stability. Because they are diffraction limited, they can focus to micron size spots, unlike the higher power lasers, which at best can focus to a 100 micron spot size. These lasers are based on the Lepton IV Series and offer a very affordable alternative to the high power lasers for Raman. This makes these lasers ideal for Raman microscopy.

For OEM

Original Equipment Manufacturer
systems, the laser has a very small body with ample mounting holes. Most lasers for Raman have a much larger body and higher power requirements. Output is a ∼2mm circular, Gaussian beam with options for a 4mm or 6mm for Raman confocal microscopy. They also last much longer, operate at lower power and can be pulsed for certain applications.

These lasers make an excellent source for confocal microscopes, scanning, optical tweezers, ophthalmetry, tissue analysis and more.

Key Features
  • 785nm 95mW, 785nm 490mW,
  • 660nm 28mW
  • 2mm circular Gaussian beam
  • Diffraction limited
  • Line widths <0.1nm
  • Power stability <1%

Technology From: Photon Systems

Pulsed Deep UV Lasers

Power Output: Over 100mW
Wavelengths: 224.3nm, 248.6nm

The DUV

Deep Ultraviolet
family of lasers are affordable and offer 224.3nm and 248.6nm. The laser is the size, weight and power consumption of a HeNe laser but with output in the deep UV. The self-contained, integrated, laser controller enables remote computer control for ease of operation and flexible data collection via LabView software. With an input power less than 10W the need for water cooling and other thermal management issues is eliminated.

The lasers reach full power in less than 20 microseconds from a cold start from any ambient temperature from -200 to 100°C without preheating or temperature regulation. With output over 100mW and line widths less than 3GHz or 0.0005nm these are great sources for a wide range of applications.
