STO Series DPSS Diode Laser Modules & Diode Bars/Stacks

1. CW 1064nm Diode Laser Pump Modules & Drivers

The work mode of gain modules is CW or QCW. The QCW module also includes conduction cooling module and water cooling module. STO series CW module maximum power is 450W. Much powerful module also can be customized upon request. Typical applications are laser amplifiers for nanosecond and picosecond MOPA lasers, gain modules for unstable oscillator resonators, CW pumped, 532nm, ns q-switched lasers, and LIDAR lasers.

Applications:

• Metal plate laser cutting, up to 12mm

• Metal & non-metal marking & engraving

• Metal & plastic welding, laser cleaning

• PCB, ceramic and solar cell engraving % cutting

• Lab & medical applications

Definition of Part Numbers: STO-XX-C-AxBB-SS-HH

• XX: output average laser power

• C: the part models of bars such as H or E

• AxBB: dimension of the Nd:YAG rod. A is the diameter and BB is the length.

• SS: the structure of the water cooling block such as CX (side), XX (bottom), XB (bottom with plate) and XG (bottom with nozzle)

• HH: the height of the optical axis.

Note: The typical Nd:YAG doping for STO series CW DPSS laser module is 0.6% and other doping levels (0.6%-1.1%) can be customized. The output power is measured with regular 300mm cavity length with flat-flat or concaved-flat resonator. The expected life time is 10,000 hours and the warranty is 12 months from the date of delivery.

2. QCW/Pulsed Diode Laser Pump Modules

Applications:

• Direct industry applications

• As laser oscillator or laser seed

• As laser amplifiers

• To get high peak power with Q-switch

• Other lab & medical applications

• High repetition rate laser rangefinder

• High pulse energy military applications

(1) mJ Level Diode Laser Pump Modules

Remark: (1) Customized stack/planar array side/end-pumping QCW modules in various shapes such as arc and annular available upon request. (2) The doping level of Nd:YAG can be customized from 0.6% to 1.1%. Pulse energy listed above is measured at 200μs/100Hz at 1064nm. Typical QCW modules are designed with duty circle £5% and higher duty circle modules must be customized. Small signal gain may be various according to different designs.

(2) Joule Level QCW/Pulsed DPSS Laser Modules

Remark: the above QCW modules are usually driven by a group of QCW Laser Diode Drivers synchronously and the operation voltage is the sum of these voltages. Pulse energy listed above is measured at 200μs/20Hz at 1064nm. Typical QCW modules are designed with duty circle ≤2%. Customized modules available upon request.

(3) Definition of Part Number: STO-TT-PW-CC-NN-PB-SS-AxBB

• TT: energy level such as GQ (mJ-level modules at 250us) and JQ (J-level modules at 250us)

• PW: total pumping peak power in W

• CC: cooling method such as W (water cooled) and C (conductive cooled)

• NN: number of bars

• PB: peak power per bar such as 100W or 200W

• SS: Structure of the modules such as H (linear array), A (arc) , C (circular). For example, H34 is linear array 3x4, 1P is one bar on each cell, 4A6 means there are 4arcs and there are 6 bars on each arc,

• AxBB: rod size. A is the diameter and BB is length in mm.
