DETAILED INFORMATION

Innovative Photonic Solution’s proprietary Wavelength Stabilized Laser features high output power with narrow spectral bandwidth. The laser’s stabilized peak wavelength remains “locked” regardless of case temperature (15 to 45 deg. C).

Devices can be spectrally tailored to suit application needs and offer side mode suppression ratios (SMSRs) better than 40 dB, thereby providing extremely high signal to noise ratio and making these sources ideal for Raman spectroscopy and pump laser applications. The laser is integrated with high performance laser drive and temperature control electronics in a compact package.

In addition to integration into systems, IPS’ OEM U-Type module is designed to “drop in” to our UL/CE and IEC certified turnkey modules to offer wavelength flexibility at a lower cost.

ELECTRICAL PINOUT

Pin	Pin Label	Function
1*	V+	Power Supply: 5V-12V. For lasers operating <600mW, a 5V minimum is required. For lasers operating >600mW, a minimum of 9V is required, 12V recommended
2^	VBIAS ENABLE (Set Enable)	For analog control: Enable external laser power control through pin 8 (LD VBIAS): High (>3.6V up to V+ supply voltage) = Enable Low (GND) = Disable The same Functionality is emulated via software as a replacement for this analog control
3	SCL/TX	I2C: SCL standard (RS232: TX; board by request)
4	SDA/RX	I2C: SDA standard (RS232: RX; board by request)
5**	GND	Ground
6*	V+	See Pin 1
7	Enable	Laser Enable: TTL High (>3.6V up to V+ supply voltage) = Enable TTL Low (GND) = Disable Pin may also be used for PW modulation at a rate of 1kHz
8^	LD VBIAS (LD Set)	Laser power setpoint – Enables analog external control of laser drive current Drive VBIAS Enable (pin2) high to enable this option Drive voltage between 0V and 1V The voltage bias will be a 1:1 ratio to the laser drive current. See Operational Note #6
9^	PD+	For analog readout. Connect voltmeter to PD+ (pin 9) and GND for photo diode V output (0V-3.3V). The same functionality is emulated via software as a replacement for this analog control
10**	GND	Ground
